Internal planning tool · Formula 1.0.0
Turn “review this regularly” into actual dates.
Choose when something was last checked and how often you want to revisit it. You’ll get a short preparation and review schedule you can print or copy into your own system.
Your internal schedule
Choose a cadence, then build the schedule.
| Review | Begin preparation | Review date |
|---|
Each occurrence is calculated from the original verified date. Month-end dates clamp to the final day of the target month without drifting future occurrences.
What the dates mean
“Begin preparation” is simply the number of calendar days you chose before each review. The schedule does not adjust for weekends, holidays, agency closures, grace periods, effective dates, or external change alerts. Save the authoritative due date and its source separately whenever an official obligation applies.
Validation record
Formula 1.0.0. Automated fixtures cover ordinary quarterly dates, end-of-month clamping, leap years, year boundaries, preparation across months, integer and date validation, upper-horizon rejection, increasing dates, exact row counts, and timezone-independent ISO output.
