      FAQ

      FAQ

      What date is 100 days from today?

      Tap “100 days from today” in Countdown, or open Add to a date, keep today as the start date and enter 100 days. Turn on “Count the start date as day 1” if you want today to be day 1.

      Does the weekday count skip holidays?

      No. Weekdays and weekend days are split by Saturday and Sunday only. Subtract public holidays yourself if you're counting business days.

      Where are my saved countdowns stored?
