When you want to calculate how much time has passed between two specific dates it is best to use dedicated utilities, no matter if they are online or on your PC.

Advanced Date Time Calculator falls into the latter category, and it can provide you with several additional functions that can come in handy.

The application features a user-friendly GUI (graphic user interface) and, even if you are a beginner, you can access whichever tab you prefer.

If you go for the first one, you can calculate what date it will be if you add several years, months, weeks or day to a specified date. Similarly, you can subtract years, months or days from a certain date.

Moreover, you can also add or subtract hours, minutes or seconds if you are looking to obtain a very exact time and date.

Due to this application, you can also calculate how much time has passed between two certain dates. You first need to enter the day, month and year either manually, or using the integrated calendar.

As soon as the two fields have been filled in, the utility automatically starts the calculation and displays the difference. You can copy the result to the clipboard, but only if you are interested in its generic form. In other words, you cannot copy the output expressed in elements, i.e. solely in years, months, weeks and so on.

Another useful function of Advanced Date Time Calculator is that it can count how many weekdays and weekends have passed between two specified dates. It also shows how many Sundays, Mondays, Tuesdays, etc. have passed.

All in all, this application can help you save time when planning events or simply converting time units from one value to another.
