Q.O.D. = every other day. Q.A.D. = every alternate day. Technically speaking, I would be hard pressed to find a difference. Nevertheless, I have spent a lifetime writing q.o.d. on prescriptions so that pharmacists can transcribe the latin abbreviation back into plain English for the patient. What a useless step!
If you want to calculate the number of days between two dates you can simply subtract the older date from the newer date. The result will be an integer that represent the days between dates. In the example, the formula in cell D6 returns 365, since there are 365 days between 1/1/1999 and 1/1/2000. Dates in Excel are simply serial numbers that start on 1/1/1900. In the example, the formula in cell D6 simply subtracts the numeric value of 1/1/1999 (36161) from the numeric value of 1/1/2000 (36526) to get a result of 365.
