About Day Count Box

Day Count Box is a set of free date and time calculators: count the days between dates, add or subtract days, work out an age, count business days and follow live countdowns to holidays and your own events.

How the answers are worked out

Every answer is calculated in your browser using your device’s own date and time zone, so pages such as “90 days from today” are correct whenever you open them. Dates follow the Gregorian calendar, with leap years included. Holidays follow US rules unless a page says otherwise.
