FAQ

Can I track multiple events at once?

Yes — save up to 5 events using the Save button. Your saved events appear below the calculator and persist across browser sessions.

Why is there no progress bar for dates beyond 1 year?

The progress bar is designed to give a visual sense of nearness. For events more than a year away, the days count alone is more meaningful than a progress percentage.
