Date/Time Calculator

New

The Date/Time Calculator handles two essential date-math tasks in one place. Use **Duration mode** to find the exact time between any two dates — broken down into years, months, weeks, days, hours, minutes, and seconds. Use **Add/Subtract mode** to shift any date forward or backward by any combination of years, months, weeks, and days, and see the resulting date instantly.
