A shared calendar for separated parents

Why one calendar beats two

Most arguments between separated parents are not about the schedule. They are about what each parent thought the schedule was. Two calendars, kept separately, drift apart within weeks: a swap agreed by text is added to one and forgotten on the other, and the next handover starts with "that's not what we said".

A single calendar that both parents see fixes the drift at the source. There is one version of the truth. When it changes, it changes for both of you.

Build one now

Set your rotation below, add the holiday rules you already know, and send the link. Your co-parent sees the same calendar, in their own colours, with nothing personal in the link.

What goes in it

• The rotation. Who has the children on which nights, with the changeover time.
• Holiday rules. Christmas, New Year, summer halves, half-terms, written as rules so they repeat or alternate without re-entry.
• Fixed commitments. School times, clubs, regular medical appointments.
• One-off events. Parents' evenings, birthday parties, trips, with who is taking the child.
• Agreed swaps, added the moment they are agreed, not the night before.

What stays out: anything that is not about the children's time. A shared calendar is not a diary of grievances.

Handling changes without a phone call

The difference between a shared calendar and a shared argument is how changes are made. A calendar anyone can edit at will becomes another thing to disagree about. The pattern that works:

1. One parent requests a change, with the dates and a short reason.
2. The other parent approves or declines, in writing, by a date.
3. If approved, the calendar updates for both, and the request stays in the record.

That is a change request, not a conversation. It is how PeaceParent handles swaps in the app, and it is worth copying even if you use something simpler: the templates here do the same thing by message.

Setting it up in ten minutes

1. Agree the term-time rotation. If you have not, the patterns explained in the 2-2-3, 2-2-5-5 and alternating weeks guides cover most families.
2. Build it above, add holiday rules, and check the twelve-month view.
3. Send the link to your co-parent. Ask them to reply with anything that does not work, by a date.
4. Once agreed, export the calendar file and import it into whichever calendar each of you uses, or open it in PeaceParent so it stays in sync from then on.
5. Print one for the fridge in each home. Children like to see it too.

What if my co-parent will not use it?

Keep yours accurate anyway, and send them the exported calendar or a printed copy whenever it changes. A surprising number of reluctant parents come round once they notice the calendar answers their questions before they have to ask them.
