### 5/5 — Excellent,free date/time calculator

*2024-11-05*

I am surprised more people have not reviewed this terrific time difference app. This app makes it incredibly easy to figure out the difference between years, months, weeks/weekends, dates, hours and seconds. The other feature is the ability to add or subtract to the same. You have the option of using a 365 day calendar or a Monday through Friday business calendar. Results can be shown in 24 hour military time or 12 hour am/pm time

The results are shown on the same screen as the calculation and, one of my favorite features, you can export those results to a file or share them by text, email etc. 

The developer also included a native iPad version, which looks great on my iPad 11 inch. AND, it is completely free with no ads**👍.

### 5/5 — Excellent,free date/time calculator

*2024-10-16*

This app has everything you need in a date and time calculator. You can figure out differences, or you can add or subtract, applying this two dates as well as times. 
The developer thoughtfully included various date modes, such as business days. The interface is dead simple to use and you can export the results. 

Given that this is a free app with no ads, I appreciated the developer created an iPad native version as well .

### 5/5 — Does what it says on the tin

*2020-12-04*

Calculates dates. Calculates time. 
Calculates date and time. Works great for everything I need from it, and the ads are not intrusive, which is a nice touch for once.

**Developer response:** Thanks for the review!
