Date & Time Calculator (9 in 1)

By Thomas Tsopanakis

This app is only available on the App Store for iOS devices.


Date & Time Calculator (9 in 1) is the perfect tool to work with time. It is by far the best and most accurate date and time calculator available for iOS!

The Time Difference Calculator works out the difference between two periods of time. How long have you been at work today? - So type in: "17:30 - 7:45 =" and you get: 09:45 (9 hours and 45 minutes).

Calculate work days between two calendar days. Exclude weekends and find out how many week days are left.

You can add or subtract time expressions defined in years, months, days, hours, minutes AND seconds

You can multiply/divide time expressions defined in years, months, days, hours, minutes AND seconds

Use this time converter to convert instantly between seconds, minutes, hours, days and years.

What date is 10 days from now, or 5 weeks from now?
With Date Ranger you can quickly determine the new date given a start date, and a date range in days, weeks, months, or years to add or subtract.

Provides time zone conversions taking into account local time zone and accepts present, past or future dates.

Age Calculator simply shows your age (years old, months and days).

Time Travel calculates the time left on your trip given total distance remaining and current average speed.

The best...

Date Time Calculator I have used on iOS—by a long way. I use it to help plot my short stories: above all I require a simple user interface that does not distract me from my primary purpose. However, I also require accuracy and a variety of calculation modes.
This app fulfils all of my requirements in spades.

Best of the lot

I use this app so often, especially calculating work days as I am a teacher and constantly remind students of days before exams etc. Thank you for making so many lives better.

Perfect for my needs

I wanted an app to estimate the date when I would finish a commission. I was using another app which was OK - then they updated it. I looked for a substitute and tried a couple but this one stood out for ease of use. I have given it 5 stars because it does everything I wanted and then some. But it would deserve even more stars if it was possible to choose working days.
