Date Calculator

Read full description

Date Calculator turns counting days into a few quiet taps. Pick two dates and read the gap in every unit at once; pick two moments and read it in hours and minutes; or take a date and shift it forward or backward by exactly the amount you need. Every Gap in One Glance Two dates, every breakdown together: total days, weeks and days, months and days, years and days, plus a tidy "years, months, days" line. Pick the unit your story needs and copy it with one tap. Numbers and date formats follow your device, so the result reads the way you already read it. Time, Not Just Dates A separate time difference mode counts hours, minutes and seconds. Turn on Cross midnight whenever the end time falls before the start and the calculator quietly carries it to the next day — handy for shifts, flights and overnight runs. Date and Time, Together The Date & time mode joins both worlds for plans that don't fit inside one day. Enter the moment you started and the moment you finished, and the gap arrives in a single clean line. Add or Subtract on a Date Pick a starting date, choose days, weeks, months or years, and the landing date appears the instant you stop typing. Great for delivery windows, project milestones, due dates, contract terms and anniversaries. Months and years respect the real calendar, so the 29th, 30th and 31st always land where the month actually ends — no surprises. Now, in One Tap Set the start or the end to Now whenever you want the gap "from today" or "until today". One button swaps start and end the moment you realize you had them the other way around. Save, Favorite, Share Tap Save to keep a calculation in your history. Swipe right on a record to favorite the ones you come back to. Long-press to remove what you no longer need. Any result can be shared as one clean line of text, ready for chats, notes and emails. Filter your history between All and Favorites with a single tap. Yours, on Your Device Date Calculator runs entirely on your device and works offline. Your history and favorites stay with the app — no account, no sign-up, nothing to set up before you start. Turn on Airplane mode and every calculation still happens at the same speed. Date Calculator counts the days; you keep the plan.
