How to use this calculator

Enter sessions with room, speaker and start/end times on one date. Add shared breaks, optional speaker availability windows, a changeover buffer and the event time zone.

The checker preserves your timetable and reports conflicts rather than moving sessions. Room or speaker reuse needs the selected elapsed buffer. A speaker without availability rows is explicitly marked unchecked. Multiple availability rows for a speaker combine.

A worked example

An opening session from 09:00-10:00 and workshop from 09:30-10:30 overlap for their shared speaker even when the rooms differ. The example reports one conflict.

Can this automatically optimize all conference tracks?

No. It checks a bounded manually arranged timetable of up to forty sessions. Review conflicts, edit session times and calculate again.

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.
