How to use this calculator
Choose the search range, candidate weekdays and minimum consecutive dates. Add availability periods for each person and any unavailable exceptions using matching names.
Every person must be available on every included date. Exceptions override available periods. Windows contain consecutive calendar dates and rank by length, then earliest start; isolated weekends remain separate windows.
A worked example
Alex available November 2-8 and Sam November 6-10, 2026 share Saturday-Sunday November 7-8. A two-consecutive-date weekend search returns one window.
Will this read or publish our personal calendars?
No. Entered date ranges stay in your browser unless you explicitly save or share a setup link. No calendar accounts are connected.
Which calendar and years are supported?
Use Gregorian dates from 1900 through 2100, with results in that range. Most daily plans allow up to 366 dates; service-budget searches allow 731. Timed intervals have exclusive ends and use browser IANA time-zone rules; nonexistent local times are rejected and repeated times require your choice. Working calendars and policy terms are entered by you. The holiday comparison uses TimeCubby's published country/region coverage. Copy, CSV and print include assumptions; calendar exports appear when dated events exist.
What happens to my dates?
Calculations run on your device. Saving a calculation is optional and keeps it in this browser. A setup link contains the dates and settings you entered; anyone with the link can read them. Use one tab per saved calculator. Clear saved data from Privacy & settings.
