Duonidus is a shared calendar for co-parents. Agree on handover days together, see the split in numbers, and avoid misunderstandings about who has the kids when.
Claim or release a day with one click. Every date is split into a morning and evening half, so a midday handover can be agreed precisely.
Write a note directly on a date — handy for handovers, birthdays, or anything worth remembering.
Want to swap a day? Request to take it over — or offer to give it up yourself. Nothing changes hands until you both agree.
Once you agree on a month, you can lock it together, so neither of you accidentally changes agreed days.
See the custody split as clear charts — total, per year, and per month.
Create a read-only link so grandparents, for example, can follow the calendar without being able to change anything.
