How can I enter number of hours and minutes spend on something?

I have a scenario where i have to enter total number of hours and minutes spent in a 3 months span? Can be in hundreds. Which widget can I use for that?

You can use a Form calculation widget for that - https://www.jotform.com/widgets/calculation

But please could you explain how exactly would you like to calculate the data? Please also let us know the form where you are trying to implement this.

Thank you for your reply. I figured it out.
