How to Use:

This calculator figures out what the date will be a certain number of quarters (3-month chunks) from a starting point or how far back a given number of quarters would land you.

Start by picking a Start Date it’ll default to today, but you can choose any date. Then enter how many quarters you want to add or subtract. Switch modes using the Add Quarters or Subtract Quarters radio buttons.

Once you enter a number or change the mode, the output updates instantly. The result includes:

  • The resulting date after adding/subtracting
  • The quarter number (like Q2 or Q4) if you toggle it on
  • The total months moved (3 per quarter)
  • And if you flip on Verbose Mode, you’ll see the full weekday and long-form date (like “Monday, March 31, 2025”)

The output flashes blue each time it updates so you always know it’s refreshed. Use the Copy Output button to grab the result, or Export it to a text file. You can also reset everything using Clear All.

Everything happens right in your browser no data ever leaves your device.
