Why this is here

Three exercises where the page gives you a starting date and expects you — or your automation tool's date functions — to compute the answer. None of these have a fixed expected value; they're all relative to today or to a freshly generated date.

1. Tomorrow's date


2. Future weekday


3. Month arithmetic + format conversion

Generate a date, then compute the first day of the second following month — e.g. 12/24/2015 → 2016-02-01 — and enter it in ISO format.

Initial state.
