Date & Time

Tools for your date and time calculations: age, duration, countdown and time zones.

The Date & Time category brings together tools for all your time-related calculations: exact age, duration between two dates, countdowns, and time zone conversion. These calculations look simple but quickly get complicated to do by hand, because of leap years, the varying number of days per month, or the time difference between countries.

Each tool gives an exact, instant result from the dates or times you provide, with no risk of a calendar mistake. They're useful for administrative purposes (calculating deadlines, due dates), personal use (birthdays, countdowns), or professional coordination with teams located in a different time zone.
