Date Calculator vs Age Calculator

How many days between two dates? Get the exact answer in one tap — no counting squares on a calendar, no math in your head. Pick a start date and an end date, and DateDiff breaks the gap down into every unit at once: years, months, weeks, and days, plus total days, total weeks, total months, and total hours. It works the other way too — add or subtract days, weeks, months, or years from any date to land on the exact day you need. Every result is calculated on-device and stays accurate across leap years and century rules. WHAT YOU GET - The precise span between any two dates in years, months, weeks, and days, all shown together - Add or subtract time to find a future or past date instantly - Business-day counting that skips weekends and imported holidays - Country holiday packs plus your own custom days off, so workday counts match your calendar - Saved date pairs with upcoming milestones and live countdowns to the days that matter - A plain-text export of your saved calculations to share or keep PERFECT FOR - Planners counting down to a trip, wedding, or big event - Anyone working out an exact age from a birth date - Project managers tracking deadlines in real working days - Curious minds settling "how long ago" and "how far away" questions WHY NOT JUST COUNT ON A CALENDAR Flipping through months and tallying days is slow and easy to get wrong — one skipped weekend or forgotten leap day throws the whole number off. DateDiff does the counting for you and stays exact every time, including the weekend and holiday skips that hand-counting always misses. PRIVACY Everything stays on your device.
