Date Time Calc is an application to calculate future and past dates adding a date interval and to calculate date difference between two assigned date
It is realised for business and technical user who are in need of calculation of date in a bullet proof way.

Do you want to know the future date adding 150 days from today?
Do you want to know the difference in years, months, days between 25 March 2009 and today?
Date Time Calc can do it.
All using the Mac standard date-time controls you already know.

Date Time Calc is absolutely easy to use because it uses 'natural' elements to compute dates (by popular demand from the user of the old release) and it was re-written to use the latest algorithms provided by Cocoa on date computations
You can add or subtract to dates, years, months, days or work with absolute precision and add or subtract days, hours , minutes and seconds to guess future and past date-times.

You can also calculate difference between two dates using calendar specification (years, months and days) or using a time precision method specifying date and time and obtaining a difference in days, hours, minutes and seconds.

Date Time Calc has no calculation buttons, adjusting date and time in two elements instantly update the result in the remaining third element.
Simply and natural as any application has to be, you will be amazed using it!

Any time you calc a date or a difference the result is also displayed in textual form on the bottom of the window.
At any time you can save the result in the log (persistent over re-launch)

Date are expressed in accordance with your preference settings.

Result can also be copied to the clipboard in textual format
06 Jan 2014 19:04:26 + ( 120days ) = 06 May 2014 19:04:26

if you use also time, the string will show it
example: 06 Jan 2014 19:04:26 + ( 120days 12hours 30min ) = 07 May 2014 07:34:26

The log can collect and save all the calculation you need to record using a command button
At any time you can clean the log resetting it.

Requires Mac OS X 10.8 or successive

- Results displayed and updated as you type
- Uses 'natural' elements to compute dates (years, months, days, hours, minutes, seconds)
- Uses 'natural' elements also to compute differences (years, months, days, hours, minutes, seconds)
- Date display using your current local settings and language
- 'Set date to now' button for fast calculation of backward and forward dates from the current date
- Calculates time difference, if requested, also using hours, minutes, seconds
- Calculates time interval, if requested, also using hours, minutes, seconds
- Result summarised also in a plain text to avoid misinterpretation
- The result can be sent to the log, saved over re-launch
- Log can be reset at any time
- Bullet proof results using Mac OS X Apple libraries to calculate and manipulate dates

Customer Reviews

Programmers Point of View

Much as the other reviewer before me stated, I really like this app. I bought version 1 (also on store) and use it daily. The one complaint I had in version 1 - I found to have in Version 2. Did I pay more, yes - but when it fits a need, its worth it. I find myself having to calculate time differences very often and this app makes doing that simple for me. The log was a cool twist and something I can see myself using a lot.

All in all, this is very user friendly and I hope the developer(s) continue to enhance this more. While buying newer versions makes sense on big releases, I hope some of those modifications happen in this version and not force loyal customers to buying every new change. (Nickel and diming kills reputations). The changes between version 1 and 2 justify the added cost though so I cant complain. Thanks for a great app.

Does a great job

This program does a great job with not only date math, but also with time.

Nice App, would like a couple tweaks

I’m a programmer, and I often want to calculate approximate rates from samples in a log file. So I know the starting and ending timestamp (in various formats), and the record count at each point. Then calc the 2 differences and then divide records/seconds to get records-per-second.

This app only helps with the date/time difference, but not deducting stars because my use-case is not what the app claims to solve.

I use the Difference tab, and then the “Time Precise” radio button. This gives me a difference in hours / mins / seconds, but then I need to do my own multiplying to convert back to seconds.

Some changes I’d like:
* Let me toggle the difference between hours/mins/seconds and just seconds; it’s nice to see both. The hours/mins/seconds is the sanity check, and then the raw number of seconds is good for calculations
* Ideally it would also let me display answers in Unix epoch format (number of seconds since 1970). This could be a third format toggle.
* Let me copy and paste random timestamps into the 2 text boxes. This would require the code to do a bit of trial-and-error guessing to get the format correct. In a pinch, maybe let me specify a format. (ideally should also support Unix epoch)

But this does save a bit of time and is a nice first step.
