(Special thanks to MisterK for migrating it to SAMMI)

Do simple math with dates. You can add and subtract minutes/hours/days/years (and more) to a specific date or the current date and time, in any format you like. You can also get the difference between two dates/times. Useful to know how much time is left until certain event.


  1. Date Math: Very powerful command with a lot of options. You can do math and format the dates/times as you want, even with text. You can also use it to get the current date and time.
  2. Date Diff: Get the difference between two dates and/or times.


One of the main features of the extension is the ability to do math in any date/time format you want, even adding text to it. You can even format a date without doing math. Read carefully the guide before playing with it.


The commands have many options. Please read the extensive documentation (with examples) in the GitHub repository before using it.
