How the calculation works

Find the smallest non-negative occurrence index whose anchored calendar date is on or after the reference date. A recurrence on the reference date is included. A reference before the start returns the start. Month/year dates stay anchored to the original day. The search handles long supported ranges without enumerating every occurrence. Dates use the Gregorian calendar in years 0100–9999 and are independent of browser timezone offsets. Calendar days have no daylight-saving duration adjustment. Outputs outside this date range are rejected.

Example

Worked example: Starting Date = "2026-10-12"; Repeat Interval = "3 months"; As-of Date = "2026-11-01". Result: 2027-01-12.

Practical tip

Check the listed dates against the actual training schedule arrangements; bank holidays and calendar exceptions require a separate decision.
