A WAy To Optimize The Completion of Multiple Events In The Same Day

[djyayo]

What I am looking for is a way to automatically calculate the most efficiant way to attend the most events in one day if the events all have different start times and lengths. Basically highlighting or bolding the event time starts in each group that will allow for a person to attend the most events in a day. Ive attatched a spreadsheet with an example of what I am trying to do.

Thanks for your help in advance.
