if someone takes personal day it is 1 occurrance

but if they have more then 1 day in a row off it is 1 occurrance

example

4/24/06 personal day 1 occurrance

6/24/06 personal day

6/25/06 personal day

instead of these being 2 single occurrances it is consider 1 occurrance for the 2 days off in a row, but this can be more then 2 days also

so what i need to show is that the person only has 2 occurrance and not 3
