Everything is explained here from scratch, one click at a time. Find what you want to do in the contents and follow the steps in order. You can't break anything: a day never changes owner without the other parent saying yes.
🧭 Before you start: how to read the calendar
Words and symbols in the calendar
When? Read this first — the rest of the guide uses these words.
Half: Every date is split into a left half (morning) and a right half (afternoon).
Period: The afternoon of one date and the morning of the next belong together — it's the time from one handover to the next. When you take, give away or take over a half, the connected half on the neighboring date ALWAYS goes with it.
Colors: Below the calendar you can see which color is yours and which is the other parent's. A half without color (just a thin border) is free.
Click: Tap or click once and let go.
Double-click: Click twice quickly. On a phone: tap twice quickly.
Long press: Hold the mouse button or your finger completely still on the spot for about half a second, then let go. This opens the note dialog for exactly the half you pressed.
⇄ on a half: A request or offer is waiting for an answer. Click ⇄ to see it.
Bold C-shaped border: The period has been offered directly to the parent whose color the border has. It is answered with a long press.
The padlock at the top (🔓 or 🔒): this is where you lock months and turn the note lock on or off.
✉ envelope: The day has a note. Blue envelope with a lock: your private note. ↻ in the corner: the note repeats.
Find the right month
When? When you need to see or change a month other than the one shown.
How to do it
Look at the month name above the calendar.
Click the arrow ‹ to the left of the name to go back a month.
Click the arrow › to the right of the name to go forward a month.
✅ What happens next: The calendar shows the chosen month. Faded dates belong to the neighboring months and can't be changed from here — switch to their own month.
Check whether the month is locked
When? Before you change anything — many things work differently in locked and unlocked months.
How to do it
Look at the padlock at the top of the calendar page.
🔓 (open lock): the month is unlocked. You can take and release days with a single click.
🔒 (closed lock) and the text that the month is locked below the calendar: the month is locked. Days can only be moved through requests and offers.
✅ What happens next: You now know which scenarios in this guide apply to the month.
👆 Free days and your own days (unlocked month)
Take a free day
When? The month is unlocked (🔓) and the half has no color.
How to do it
Find the date in the calendar.
Decide whether you want the morning (left half) or the afternoon (right half).
Click that half once.
✅ What happens next: The half turns your color immediately — and so does the connected half on the neighboring date. If you click the afternoon of the 8th, for example, you also get the morning of the 9th. The other parent doesn't need to approve anything.
💡 Good to know: If the other parent takes the same half at exactly the same moment, you get a message that it was just taken.
Release a day you have taken
When? The month is unlocked (🔓) and the half has your color.
How to do it
Click your half once.
✅ What happens next: The half and the connected half on the neighboring date become free again.
💡 Good to know: If you'd rather give the day directly to the other parent so they have to agree to take it, see “Offer your own day to the other parent”. Don't double-click your own day in an unlocked month — it releases it and takes it again.
🙋 Take over the other parent's day
Request to take over a day — on a computer
When? The half has the other parent's color. Works in both locked and unlocked months.
How to do it
Double-click the half.
A box asks whether you want to take over this day. Check the date in the text.
Click “Yes, send request”. If you change your mind, click “Cancel”.
✅ What happens next: A ⇄ appears on the half. The day still belongs to the other parent until they accept. If they have notifications turned on, they are told right away.
💡 Good to know: A single click on the other parent's day does nothing — you only get a small message telling you to double-click.
Request to take over a day — on a phone
When? The half has the other parent's color. Works in both locked and unlocked months.
How to do it
Hold your finger still on the half for about half a second, then let go.
The note dialog opens. Tap the button “Request to take over this day”.
The confirmation box appears. Tap “Yes, send request”.
✅ What happens next: A ⇄ appears on the half, and the other parent can now accept or decline.
💡 Good to know: If a long press doesn't open the note dialog, the note lock is on — see “Turn the note lock on or off”.
See or cancel your own request
When? You have sent a request and there is a ⇄ on the half.
How to do it
Click the ⇄ on the half.
A box shows that the request is pending.
Click “Cancel request” to withdraw it — or “Close” to leave it.
✅ What happens next: If you withdraw it, the ⇄ disappears and the day stays with the other parent.
Answer when the other parent wants to take over your day
When? There's a ⇄ on one of your halves, or a request box pops up when you open the calendar.
How to do it
If the box isn't already open, click the ⇄.
Check which date the request is for.
Click “Accept” to give the day to the other parent — or “Decline” to keep it.
✅ What happens next: Accept: the period changes to the other parent's color. Decline: nothing changes and the ⇄ disappears.
🎁 Give days to the other parent
Offer your own day to the other parent
When? The half has your color. Works in both locked and unlocked months.
How to do it
Hold the mouse button or your finger still on your half for about half a second, then let go.
The note dialog opens. Click the button “Offer this day to the other parent”.
✅ What happens next: The period gets a bold C-shaped border in the other parent's color. It keeps your color — the day is still yours until the other parent accepts. If they have notifications turned on, they are told.
💡 Good to know: If you click the day once while the offer is open, you get a reminder of how to undo it.
Offer a free day to the other parent
When? The half has no color and you want the other parent to take it. Works in both locked and unlocked months.
How to do it
Hold the mouse button or your finger still on the free half for about half a second, then let go.
The note dialog opens. Click the button “Offer this day to the other parent”.
✅ What happens next: The period gets a bold C-shaped border in the other parent's color. It stays free until they accept.
Cancel your offer
When? There's a bold C-shaped border in the other parent's color on a day you offered.
How to do it
Hold the mouse button or your finger still on the day with the border for about half a second, then let go.
Click the button “Cancel offer”.
✅ What happens next: The border disappears and the day is as before.
Answer when the other parent offers you a day
When? There's a bold C-shaped border in YOUR color on a day.
How to do it
Hold the mouse button or your finger still on the day with the border for about half a second, then let go.
Click “Accept the takeover of this day” to take the day — or “Decline the offer”.
✅ What happens next: Accept: the period turns your color. Decline: the border disappears and the day is as before.
💡 Good to know: No box pops up by itself for this kind of offer — you have to open the day yourself. If you click it once, you get a reminder.
Give away your day in a locked month by double-clicking
When? The month is locked (🔒) and the half has your color. (This is an alternative — a long press works too.)
How to do it
Double-click your half.
A box asks whether you want to give away this day. Check the date.
Click “Yes, offer the day”.
✅ What happens next: A ⇄ appears on the half. The other parent clicks the ⇄ and chooses to take the day or not. You can click the ⇄ yourself and choose “Cancel offer”.
🔒 Locked months and the note lock
Propose locking a month
When? You agree on the month's schedule and want to avoid accidental changes.
How to do it
Go to the month with the arrows ‹ and ›.
Click the padlock 🔓 at the top.
Choose “Month lock”.
A box asks whether to lock the month. Click “Yes, send request”.
✅ What happens next: The month is only locked once the other parent has accepted. Until then, the text below the calendar shows that you are waiting.
💡 Good to know: To undo it: click the padlock, choose “Month lock” and click “Cancel request”.
Answer a request to lock or unlock
When? A box pops up, or the text below the calendar says the other parent wants to lock or unlock.
How to do it
If the box isn't open, click the padlock and choose “Month lock”.
Click “Accept” or “Decline”.
✅ What happens next: Accept: the month is locked (or unlocked). Decline: nothing changes.
Unlock a month
When? The month is locked (🔒) and you need to be able to click days back and forth again.
How to do it
Click the padlock 🔒.
Choose “Month lock”.
Click “Yes, send request”.
✅ What happens next: The month is unlocked once the other parent accepts.
Turn the note lock on or off
When? You keep opening notes by accident when scrolling on your phone.
How to do it
Click the padlock at the top.
Choose “Turn on note lock” (or “Turn off note lock”).
✅ What happens next: With the note lock on, a long press doesn't open the note dialog. It only applies to the device you turn it on for.
💡 Good to know: The note lock also blocks the buttons inside the note dialog (offer, request, accept). Double-clicking and clicking ✉ still work.
📝 Notes and repeating notes
Write a note
When? You want to write something on a date, e.g. “Handover at 3 pm” or “Dentist”.
How to do it
Hold the mouse button or your finger still on the date for about half a second, then let go.
Type your text in the top field.
Click “Save”.
✅ What happens next: The date gets a ✉. Both parents can see the note, and it is also shown on share links.
💡 Good to know: If you write the Danish words “fødselsdag” (birthday) or “vandretur” (hike), the note automatically gets the icon 🎂 or 🏕️.
Read a note
When? There's a ✉ on a date.
How to do it
Click the ✉ to open the note.
To see all notes directly in the calendar, click the button “Show notes: Off” so it changes to “Show notes: On”.
✅ What happens next: The note text is shown in the calendar cells instead of the envelopes.
Edit or delete a note
When? A note needs changing or removing.
How to do it
Open the note (click the ✉ or long-press the date).
Change the text and click “Save” — or click “Delete note”.
✅ What happens next: The note is changed or gone for both parents.
💡 Good to know: If the note is part of a repeat (↻), you are asked whether the change applies to this note only — see “Edit a repeating note”.
Write a private note
When? You want to remember something yourself that the other parent shouldn't see.
How to do it
Hold the mouse button or your finger still on the date for about half a second, then let go.
Type in the private note field (the bottom field).
Click “Save”.
✅ What happens next: The date gets a blue envelope with a lock. Only you can see it — never the other parent and never on share links.
💡 Good to know: Delete a private note by emptying the field and clicking “Save”. The “Delete note” button only deletes the shared note.
Give a note a colored category (paid add-on)
When? You want to tell school and activities apart at a glance.
How to do it
Create your categories (name and color) under “My profile”.
Open the note with a long press on the date.
Choose the category in the list below the text.
Click “Save”.
✅ What happens next: The note is shown in the category's color in your calendar.
Create a repeating note
When? Something happens regularly, e.g. “Swimming” every Tuesday or “Football” every other Saturday.
How to do it
Hold the mouse button or your finger still on the FIRST date for about half a second, then let go.
Type the text in the top field.
Click the button 🔁 “Repeat note”. New options appear.
Choose “Every week” or “Every 2 weeks”.
Check the date next to “Repeat until”. It is set to one year ahead; change it if it should be shorter. It can be at most two years ahead.
Click “Save”.
✅ What happens next: You get a message saying on how many dates the note repeats. All the notes have a small ↻ in the corner of the envelope.
💡 Good to know: If one of the dates already has a note, it is skipped — the message tells you how many.
Edit a repeating note
When? The text needs changing, e.g. from “Swimming” to “Swimming at 5 pm”.
How to do it
Open the note on the first date the change should apply from.
Change the text and click “Save”.
A box asks which notes should be changed.
Click “This note only” to change just this date — or “This and all following” to change this one and all later ones.
✅ What happens next: This note only: the date is changed and taken out of the repeat. This and all following: all later notes in the repeat are changed; earlier notes stay as they were.
Delete or stop a repeating note
When? A single session is cancelled — or the activity stops altogether.
How to do it
Open the note on the date in question (to stop it: the first date that should NOT be there).
Click “Delete note”.
Click “This note only” to delete just that one — or “This and all following” to stop the repeat from that date.
✅ What happens next: The chosen note — or it and all later ones — is deleted. Earlier notes are kept.
🛟 When something doesn't work
Nothing happens when I click a day
When? You click, but the day doesn't change color.
The month is locked (🔒): you get a message saying so. Use requests and offers instead.
There's a request or offer on the period: you get a message about it. Answer it via ⇄ or a long press first.
It's the other parent's day: a click does nothing — double-click to request to take it over.
The date is faded: it belongs to the neighboring month. Switch month with ‹ or ›.
I can't see the buttons for giving away or taking over
When? The note dialog is open, but the button is missing.
If you opened the note by clicking the ✉, the buttons aren't shown, because Duonidus doesn't know which half you mean. Close the dialog and long-press the half itself.
If there's already a request with ⇄ on the period, it is answered via the ⇄ instead.
A long press doesn't open the note dialog
When? You hold your finger down, but nothing happens.
The note lock is on: click the padlock and choose “Turn off note lock”.
You moved your finger slightly: then it counts as scrolling. Keep your finger completely still.
Why does the neighboring date change color too?
When? You clicked one half, but two halves changed color.
The afternoon of one date and the morning of the next are one period (from handover to handover), so they always go together. This makes sure the child is always with one of you for the whole night.
