How do you calculate the days until a date?

A countdown calculator measures the time from the moment you press Calculate to a chosen date, broken down into days, weeks, hours and minutes. For a past date it shows how long ago it was instead. For example, if today is 21 June 2026, the countdown to 1 January 2027 shows roughly 194 days remaining.
