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 in one click.

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 format are expressed in accordance with your preference country settings.

Result can also be copied to the clipboard in textual format

example (some european country format selected in system pref):

17 Jul 2017 + ( 120 days ) = 14 Nov 2017

if you use also time, the string will show it (USA format selected in system pref)

example: Jul 17, 2017, 6:49:50 PM + ( 150 days ) = Dec 14, 2017, 6:49:50 PM

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.

• 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

• It can add or also subtract time

• Result summarised also in a plain text to avoid misinterpretation

• The result can be sent to the log, saved over re-launch
