I have 2 columns start and stop I want to count the number of start stop events according to the following rules 

counting starts when first discharge occurs

• any start in the first 12 hour block is counted as 1 event

• any new start in the next and subsequent 24 hour blocks are each counted as 1 additional event

• this counting continues until there is a 24 hour block with no event.

• for the next event after 24 hour block with no event, the sequence begins again

Could anyone help me please
