Calculate the next scheduled date in a repeating academic or term calendar. The calculator runs entirely in your browser and pairs a focused answer with the method, assumptions and the related tools worth checking next.
Your inputs stay in this browser tab. Nothing is sent to a server to produce the result.
Review the inputs and select Calculate.
Enter the first date of a repeating schedule, the date you are planning from, and a repeat interval in days, weeks, months or years. The calculator steps the schedule forward and returns the first occurrence after your planning date, how many days away it is and its weekday.
Starting from the first date, the interval is applied again and again until the schedule passes the planning date; that next occurrence is the result. Month and year steps keep the same day number where they can, and clamp to the month’s last day when they cannot.
A schedule starting Monday 7 September 2026 and repeating every 2 weeks runs 21 September, 5 October and 19 October; planning from 20 October 2026, the next date is Monday 2 November 2026, 13 days away.
Clamped month steps do not return to the original day: monthly from 31 January 2026 gives 28 February, then 28 March — the 31st is not restored. The planner repeats a simple fixed interval only; it does not model term breaks, holidays or exceptions in a real academic calendar.
Enter the first scheduled date, the date you are planning from and the repeat interval, then select Calculate to see the next occurrence. Each step below is a short action rather than a wall of explanation.

Enter the first date of the repeating schedule — every occurrence is stepped forward from it.
Enter the date you are planning from, plus the Repeat every amount and the Interval unit — days, weeks, months or years.
The first occurrence after your planning date, with its weekday and days away: a schedule starting Monday 7 September 2026, repeating every 2 weeks, next falls on Monday 2 November 2026 from 20 October 2026 — 13 days away.
Use exact source inputs, keep the reference date visible and verify any official rule separately.

The next date in a repeating schedule. Enter the first date of the schedule, the date you are planning from, and a repeat interval in days, weeks, months or years; it returns the first occurrence after your planning date, how many days away it is and its weekday.
It steps the schedule forward one interval at a time from the first date until it passes the planning date. A schedule starting Monday 7 September 2026 and repeating every 2 weeks runs 21 September, 5 October and 19 October, so planning from 20 October 2026 the next date is Monday 2 November 2026, 13 days away.
Month steps keep the same day number where they can and clamp to the month's last day when they cannot — and a clamped step does not return to the original day: monthly from 31 January 2026 gives 28 February, then 28 March, not 31 March.
Yes. The repeat interval can be counted in days, weeks, months or years, and the planner applies that same fixed interval at every step until it passes your planning date.
No. The planner repeats a simple fixed interval only; it does not model term breaks, holidays or exceptions in a real academic calendar, so check the result against the actual calendar.
