Calculation Guide & Reference

Generating Recurring Date Schedules & Calendar Export Mathematics

Generate repeating schedule dates for daily, weekly, bi-weekly, monthly, quarterly, or custom intervals. Free recurring date calculator with weekend shifting, holiday awareness, and iCalendar (.ics) / CSV export.

Standardized Mathematical Formula
Occurrence_N = Start_Date + (N - 1) × Interval

Each occurrence date is computed by adding a fixed interval (in days, weeks, months, or a custom day count) to the start date, repeated for the requested number of occurrences.

Variables:
Start_Date:The first occurrence date
Interval:Daily, Weekly, Bi-Weekly (14 days), Monthly, Quarterly, Yearly, or a custom day count
N:Occurrence number (1st, 2nd, 3rd, ...)
How It Works (Step-by-Step)
  • 1Enter the first occurrence date and choose a frequency (Daily, Weekly, Bi-Weekly, Monthly, Quarterly, Yearly, or a custom day interval).
  • 2Set the number of occurrences you need generated.
  • 3Optionally select a country to flag statutory public holidays, and enable "shift to next business day" for occurrences that land on a weekend.
  • 4Review the generated schedule table, then export it as an iCalendar (.ics) file for Google Calendar/Outlook/Apple Calendar, or as a CSV spreadsheet.
Real-World Numerical Example
Generating a Bi-Weekly Payroll Schedule

An employer needs 4 bi-weekly payroll dates starting from a Friday pay date.

•Occurrence 1: Start date (Day 0).
•Occurrence 2: Start date + 14 days.
•Occurrence 3: Start date + 28 days.
•Occurrence 4: Start date + 42 days.
Result: 4 pay dates spaced exactly 14 days apart, each automatically shifted forward if it falls on a weekend or public holiday.

Frequently Asked Questions (FAQ)

Bi-weekly means every 14 days regardless of the calendar, producing 26 occurrences a year (sometimes 27). Semi-monthly means twice per calendar month on fixed dates (e.g. the 1st and 15th), producing exactly 24 occurrences a year.

Yes, download the generated schedule as an .ics file and import it into Google Calendar, Outlook, or Apple Calendar — each occurrence appears as a separate calendar event.
