Date & Time
Dates are deceptively tricky: months have different lengths, leap years insert an extra day, and 'one month from now' depends on where you start. The date and time calculators in this section handle those edge cases properly. Calculate an exact age in years, months, and days — including totals in weeks and days and a countdown to the next birthday. Count the days between two dates with an optional business-day view that skips weekends. Add or subtract years, months, weeks, and days from any date, with month-end dates handled the way calendars actually behave. Add and subtract hours, minutes, and seconds for timesheets and media editing. Every result is computed against your device's local calendar, so what you see matches the date on your phone or computer.
