DAYS360
does not calculate what you want, i.e. the number of days passed between the two dates. Use simple subtraction (-
) or MINUS()
. I made an updated copy of @DrCord’s sample spreadsheet to illustrate this.
Are you SURE you want DAYS360? That is a specialized function used in the financial sector to simplify calculations for bonds. It assumes a 360 day year, with 12 months of 30 days each. If you really want actual days, you'll lose 6 days each year. [source]
