What's the easiest way to schedule?

Question

PHP

There was such an idea-task .. to make something like a schedule, like a school one, I guess.
Arrange time intervals on one side, events on the other.
Everything seems to be simple ... a banal table.
You will need drag and drop so that you can easily swap places and everything is overwritten in the database ...
fullcalendar will not work ...
maybe someone has come across solutions?

UPD: something like ... difficult to do?)

UPD2: I dug more on the net ... I will clarify the main point - the biggest problem is to "tie" the time ... that is, if at 13-40, then it is at 13.40 visually .. and not in the column 13.00 with a postscript at 13.40
UPD3: 4 subscriptions.. going for a record... and zero replies.. night...
