I have employees hired different months of the year and I have to calculate their sick time from date of hire. For existing employees the formula we use to calculate 1/2 day for sick time each month and the formula that I use is: =month(today())/2 for year beginning in January. When I have an employee starting in other months what formula do I use to calculate 1/2 days from start of employment. Example I have employee starting in September what formula do I use.
