About this app

Age & Date Calculator helps you go beyond a simple “how old am I?” number. Whether you’re curious about exact age, measuring time between two dates, or counting down to a birthday, this app gives clear, detailed results on your phone.

WHAT YOU CAN DO

• Age calculator — See your age in years, months, days, hours, minutes, and seconds, updating live. View how many calendar days you have lived and save a snapshot to History.

• Date difference — Enter two dates and get the span in total days, full weeks, and calendar months, plus weeks with leftover days.

• Day of year — Instantly see which day of the year a date is (for example, day 100 of 365 or 366), how many days are left in that year, and a simple progress percentage.

• Birthday countdown — See how many days remain until your next birthday, the date of that next birthday, your Western zodiac sign, and a traditional birthstone for your birth month.

• History — When you choose “Save to history” on a tool, a short summary is kept on your device so you can review past results. Delete individual items or clear everything when you like.

WHO IT’S FOR

• Anyone curious about detailed age or time-between-dates.
• People estimating work tenure or similar spans.
• Students and planners working with deadlines and milestones.
