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.

Just The Thing

As a writer, I'm always in the market for apps that can provide the one thing or two that you just don't realize would be handy until you see it. In terms of my writing life, this app is a fantastic tool for fact-preparation or even fiction brainstorming - and in terms of being just another dude with an iPad...well, it's simply wickedly cool. I know, I're sayin' to yourself right now: "What would I really need this for?" Trust me...if you think you don't want this utility...just try it. You'll find out. This is one of about three apps I've ever used/owned/experienced that compelled me to MAKE A POINT of contacting people I know to see if they had heard about it yet. Kudos to the developer. Seriously.

NOT for Pilots! DON’T buy it until it is fixed.

This app is not for pilots. We need to add multiple flights together and produce total hours and minutes.

This app will not do this.

If you want to add three series of flights together such as 21:48 + 18:33 + 9:19 = 49:40. This app will only add two of these trips together. When you do this you get a product in DAYS, Hours & Minutes. If you want to add three times you need to write down the product of the first two times then input this time and add the third time. The product of these times is again produced in DAYS, Hours & Minutes. This is totally in adequate for pilots who are trying to add total hours and minutes together and DON’T want them converted to days, hours & minutes.

The input method is clumsy too. In order to input 21:48 + 18:33 you need to first select the hours field then input 21, then select the minutes field and input 48, then select the next hours field and input 18 and finally select another minutes field and input 33. When all of that is done you get a product that is in DAYS, hours and minutes and hopefully you don’t need to add any other times because the process will need to start all over again.

This app needs to have a “lite” version so you can see the manner in which the app works before you commit to purchasing it.

Interesting and Useful

Downloaded as a freebie. I work in a hospital as a case manager. Close to 100% of use will be devoted to adding days to current or a recent date. Spot on.

The interface is on two levels. I like the type of menu selection scheme the developer chose. No mistaking what you want. Once in the calculator, it is equally clean in design and clear in purpose. I'd like to see a "Done" button on the number board to close. Touching off the keyboard accomplishes the same. Notwithstanding, I'd prefer a close and commit key. I certainly won't remove a star in the rating because of my quirky preference.

This app is updated and improvements are likely to keep coming. That means this "Time Machine" will be sitting next to my computer at work. Good job.
