Frequently Asked Questions
Does this check anyone’s calendar?
No. The result uses only the daily hours you enter. It does not exclude weekends, holidays, existing events, or travel.
Why can a meeting show different dates?
Midnight happens at different instants around the world. Each selected slot shows the local start and end date for every location.
What does the calendar file contain?
One event with UTC start and end times. Your calendar displays it in its own time zone. This is an import file, not an invitation; it does not send messages. Rules come from your browser’s time-zone database, so keep your browser updated.
