Calculating age in minutes can be helpful for various purposes, such as finding the duration of a process or measuring the elapsed time since an event occurred. Google Sheets provides several functions that make it easy to calculate age in minutes.

Calculate the Minutes
Here’s how you can calculate age in hours using Google Sheets:
 Enter the date and time you want to calculate the age from in one cell and the current date and time in another cell. For example, if you calculate the age of a project from the start date and time, enter the start date and time in cell A2 and the current date and time in cell B2.
 In another cell, enter the following formula:
=(B2A2)*24*60. This formula
subtracts the start date and time from the current date and time, giving the elapsed time in days. It then multiplies the result by 24 to convert the elapsed time to hours and then by 60 to convert the elapsed time to minutes.  The result will show the age of the project in hours.
For example, if you apply this formula to a project that started on May 1st, 2023, at 10:00 AM and the current date and time is May 11th, 2023, at 2:30 PM, you’ll get the result “244.50 hours”.
⚠️ For a dynamic result that shows the current age, use the NOW function for the value in B2
.
