Couldn't you just add them.

We have to deal with start time, formatting issues, lots of calculations, and more. A package called Carbon can help make dealing with date/time in PHP to a very useful package that makes it a breeze to deal with times in PHP. For instance, when creating a trial period for a user, you will want the trial. https://www.mycardstatement.us/

Thank You.!

I came across this older discussion and wanted to add something quick: you can loop through each lesson’s duration, turn it into a Carbon interval, then add them up using CarbonInterval::add. In the end, use totalHours or totalMinutes on the final interval. Curious if anyone has tried storing durations as seconds instead to make summing even easier.

I just loop through the lessons, parse each duration with CarbonInterval, then add them together. Something like: total = CarbonInterval::seconds($lessons->sum('duration_in_seconds'))->cascade();
