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.

21 Dec 2018 + ( 120 days ) = 20 Apr 2019
if you use also time, the string will show it
example: 31 Dec 2018 at 12:54:44 + ( 150 days, 12 hours, 30 min ) = 31 May 2019 at 01:24:44
