OK so I have a long list of drugs and the frequency and number they are taken during the day.

This give me a daily total used per drug

I divide the total number of each type of tablets in my possession by the number needed per day

I then have the number of days each drug will last

Question. How can I get a date that the tabs will run out. For example my sheet might say I have 45 days supply. How can I turn that 45 into a date that we will run out of drugs. Thanks
