Custody calendar and schedule maker

School breaks and shared periods

Enter the dates of each period yourself (first and last day included): they replace the regular schedule. With half and half, the chosen parent has the first half in even years and the second half in odd years; with alternating years, they have the whole period in even years. The year that counts is the year of the first day.

    Special days

    Birthdays, Mother's Day, Father's Day, events: the daytime goes to the chosen parent, the night follows the schedule. A simple marker assigns nothing.

        A day counts for the parent who has the child at noon: a morning exchange gives the day to the receiving parent, an afternoon exchange leaves it with the parent handing over. An overnight counts for the parent the child sleeps with.

        A planning tool: it does not replace a court order or an approved parenting plan. Everything is calculated on your device; nothing is sent.

        A custody schedule both homes can read at a glance

        This custody schedule maker turns a parenting time pattern into a full-year calendar. Each day shows the color and pattern of the parent the child is with (stripes for one, dots for the other, plus a letter), so the printout still works in black and white and for color-blind readers. It counts days and overnights in each home, prints the year on one page and builds a calendar file. The parents appear under labels you choose, "Parent A" and "Parent B" by default.

        How to build your calendar

        1. Pick a Custody schedule: Alternating weeks (week on, week off), Even / odd weeks, 2-2-3, 2-2-5-5, 3-4-4-3, Every other weekend or Custom schedule.
        2. Set the Start date, the Parent who starts, the Exchange day and the Exchange time.
        3. Open School breaks and shared periods to enter winter, spring and summer break, then Special days for birthdays and holidays.
        4. Click Print the year (landscape), Calendar (.ics) or Copy the sharing link.

        Common custody schedules, side by side

        Week on, week off keeps exchanges to one a week; the trade-off is seven days away from the other parent. The 2-2-3 custody schedule shortens those gaps and adds exchanges. Starting Monday, January 5, 2026, the tool shows the 14-day sequence A A B B A A A B B A A B B B. Over 2026 that gives Parent A 183 days and 183 overnights (50.1%) and Parent B 182 (49.9%), with 156 exchange days. 2-2-5-5 gives each parent the same weekdays every week. 3-4-4-3 sits in between. Every other weekend, Friday evening to Sunday evening, fits a primary home with one parent: 52 days and 52 overnights in 2026 for the weekend parent, or 14.2%.

        The counts follow a simple rule: a day goes to the parent who has the child at noon, an overnight to the parent the child sleeps with. A 3:00 PM school pickup leaves that day with the parent handing over; an 8:30 AM drop-off gives it to the receiving parent.

        Even and odd weeks

        Some agreements say "even weeks with one parent, odd weeks with the other". The tool uses ISO week numbers, Monday to Sunday, shown in the "Wk" column. Note that 2026 has 53 ISO weeks: week 53 (December 28, 2026 to January 3, 2027) and week 1 of 2027 are both odd, so the same parent has two weeks in a row.

        School breaks and special days

        Break dates vary by school district and year, so the tool has no built-in school calendar: you type them in. For each period choose Half and half or Whole period, alternating years. With winter break from Saturday, December 19, 2026 to Sunday, January 3, 2027 (16 days) and Parent A first in even years, Parent A has December 19 to 26 and Parent B December 27 to January 3; in 2027 the order flips. A special day, such as Mother's Day or a birthday, gives the daytime to the chosen parent and leaves the overnight unchanged.

        Smoother exchanges and sharing

        Exchanges at school avoid tense doorstep moments, and a bag that travels with the child (medication, homework, a favorite toy) helps. The sharing link stores your settings after the # in the address, so the other parent opens the same calendar. The .ics file holds one event per stretch, such as "With Parent A" from Monday 6:00 PM to the next Monday 6:00 PM. Nothing is sent anywhere.

        This is a planning tool. If you disagree, your court order or approved parenting plan prevails; a family mediator can help.

        Frequently asked questions

        Why does the week start on Sunday?

        The US layout starts weeks on Sunday. The "Wk" number belongs to the Monday of that row, as ISO numbering requires.

        Can I use a schedule that is not listed?

        Yes. Choose Custom schedule and type the days in turn, such as 4-3 or 5-2-2-5.

        Do the percentages match a child support worksheet?

        Not necessarily. States count overnights in different ways, so check the rules that apply to you.

        Is my information stored?
