This Windows program enables to calculate various aspects regarding time and date. The application might prove to be of good use if you need to easily find out what's the current time in a different time zone, find out how many days are left until you reach a certain deadline, etc.
Advanced Date Time Calculator gives you access to 6 tools, each with their own separate panel and output settings. I tested all of the built-in utilities and they all provided me with accurate results within moments.
In my testing, I used the Time & Date tool to learn which weekday will be on the 26th of September 2020, the Converter utility to figure out how many seconds a year has, and Time Zone to find out what's the current time in New York. You don't need much computer experience to use this app is it's very intuitive and you can immediately get the results you need.
The only aspect you need to consider before buying this app for your computer is that you can find cheaper solutions. For example, there are various online services that provide you with similar types of calculations and offer you accurate results.
Still, it's worth purchasing this program if you wish to avoid using your default web browser to make time and date calculations and plan on using this app often.
