Fonctionnement
The engine repeatedly applies the selected interval with calendar-aware arithmetic. Values are normalized before calculation to avoid ambiguities caused by input formats. Calendar operations work with structured dates and, when time zones are involved, IANA zones and the browser daylight-saving rules are used. Results are recalculated locally whenever an input changes, without sending your data to a server.
Prepare a deadline, meeting or date series without manual arithmetic.
Verify a gap, recurrence or conversion before copying it into your calendar.
Compare dates or times with consistent and repeatable rules.
