DateTime - Date and Time Calculator App Reviews

This is a one of a kind app!

I have to agree with Spoinlar. It crashes on any calculation in BCE. before the update, it worked fine. I was using it for astronomical/time calculations. Not worth it to me right now. Please fix.

This is a great app, but it definitely needs an option for calculating business days.

This is one of my top ten favorite apps. I use it at work nearly everyday while calculating delivery dates for projects.

This is a most awesome app. It is so easy and simple to use. Grate job.

I use DateTime very often. Just prior to writing this review I needed to determine 331 days from a date next year to book air travel with frequent flyer miles. DateTime did this quick, easily, and accurately.

I have been looking for such an app for a long time. Just right. Thanks. Five stars all the way

Just a couple of feature suggestions I would like to submit for consideration that need to be in a future update of this app... 1. A way to make date and time calculations with "business days" specifically in mind. For example, how many "business days" until this contract expires from todays date or any date. 2. A way to incorporate date "and" time calculations together in all calculations. For example, if I wanted to know precisely how much time is between February 10, 1995 at 09:17 AM and September 12, 1999 at 8:12 PM. 3. The "multiply" and "divide" operators need to be activated and useable in the app. So that users, for example, could perform some of the following calculations: What is 1 year divided by 5 days? Answer: 73 days. What is 3 weeks multiplied by 7 days? Answer: 147 days. And of course as your app already does, that the user can simply take that same answer that is given in "days" for example, and instantly convert it into "weeks" by clicking the appropriate button. 4. Retina Display update.

I love this app! It does exactly what I originally got it for and so much more. Example uses: I calculated how old I will be when the time capsule at the zoo is opened. Freeway signs in TN tell how many total freeway fatalities have occurred to date, and I used this app to calculate how many there have been, on average, per day. Date and time calculations like the previous commenter asked for can be done, but the method is a little convoluted. Two features I would like to see added: the ability to copy the results, so I can paste them into another app, such as email; and a backspace, so I dont have to redo a whole calculation if I enter on wrong number.

This is such a great app. I cant add much praise beyond the previous reviews. It just desperately needs an update to fit the iPhone 5 screen.

Easiest, fastest, and most functional time calculator I found on App Store ... And elsewhere. While it works and looks fine on iPad with the 2x display the iPad features to scale iPhone apps, I still wish this would become a universal app. I know... I am nitpicking... ;-) Great work. It simplifies my life namely when computing off-site time/return dates for my datacenter backups. Thanks!

Exactly what I was looking for. Very simple to use, works well.

Wow it says it cannot divide or multiple time....seems my math teacher years ago differs with this. Last time I checked 1 hour / 2 = 30 minutes. That capability is doable unless you want an app without all the known features it most assuredly should have!

I have been using this app for years and love it! Unfortunately it has started crashing. Please fix :( Ej

This is easily one of the 5 most valuable apps on my iPhone and iPad (yes, it scales beautifully on the iPad screen in portrait), and the one app with no reasonable replacement. For anyone who needs to calculate days and deadlines, this is the best app I can recommend.

I cannot express how much I love this app. It makes date calculations so fast, easy, and accurate. My life is definitely made easier because of it. Very simple, but elegant App. The only way it can get better is if they add a working week option.

Ive been using this calculator for years, as part of "CityTime". Its by far the best date calculator in the App Store, with a flexibility unmatched anywhere else. Ive always wondered why this App was twice the price of "CityTime". The only missing feature is multiplying or dividing a time period by a number.

Love the App, but please fix. It now crashes when converting time ever since I upgraded to the new iOS.

I cant get mine to work anymore- it crashes every time I try to convert months or years to days

This used to be my go to time span calculator app. However the app hasnt been updated in years and crashes when converting a time span to hours on my iPhone 6 Plus running iOS 9.2. This makes it useless for me.
