How we calculate dates

Every countdown runs in your browser and uses your device's clock and time zone, so the numbers match your local day. "Business days" means Monday to Friday, skipping U.S. federal holidays on their observed dates.

Holidays with fixed rules, like Thanksgiving (the fourth Thursday of November) or Easter (calculated with the standard Gregorian Easter algorithm), are computed directly. Equinoxes and solstices use Jean Meeus's astronomical algorithms and match published times to within about a minute.

Holidays that follow a lunar calendar, such as Diwali, Holi, Hanukkah, Chinese New Year, Ramadan and the two Eids, use published calendar dates. Islamic dates are expected dates and can move by a day depending on the sighting of the moon, which we note on those pages.
