Date Math Kit

Workflow

1. 1) Pick the unit that matches the decision

   Use Days From Today or Weeks From Today when you care about the date. Use Hours From Now or Minutes From Now when you need an exact time.

2. 2) For deadlines, decide if counting is inclusive

   The day/week tools include an option like “Include today”. This is the classic confusion behind “due in 7 days” vs “due 7 days after today”. Toggle it once and stick to the same convention across your docs or emails.

3. 3) For reminders and ETAs, compute the exact local time

   Use the hours/minutes tools to calculate an end time for meetings, breaks, cooking, or delivery ETAs. Results are based on your device clock and timezone.

4. 4) sanity-check with a second unit

   If something feels off, recompute using a different unit (for example, “90 minutes from now” vs “1.5 hours from now”) to confirm you didn't mix conventions.
