> [@new Date-time Math](https://community.glideapps.com/t/date-time-math/15963): > > The Math column can now do math with date/times. In particular: Subtracting two date/times produces a duration, which is a number and is measured in days, like in Google Sheets. Adding a duration (number) to a date/time, or subtracting it from a date/time will add/subtract that many days to it. You can pick “Now” as a substitution for a variable. More coming later today. --- _[View the full topic](https://community.glideapps.com/t/general-project-date-task-thoughts-reluctance/15629)._
