Hi guys, I need a calculator for my studies with an additional feature like calculating time duration. Maybe you can recommend me some good online calculator?

I want to say that now on the Internet a huge amount of different online calculators with different additional functions, among them with the ability to count the time and all of them are similar to each other so I think there is no point in looking for a dedicated calc you can for example take advantage of this calculator, which will easily calculate how much time https://www.calculator.io/time-duration-calculator/.
