Notes and limits

Use this sheet for venue booking, publishing, classes, travel handoffs and repeating weekday checks.

Method

The page walks local Gregorian dates at noon

The calculator creates each candidate date as a browser Date object at local noon, tests its weekday number, and prints matching dates plus a separate repeating interval sequence.

Formula

Match when date.getDay() equals the selected weekday. Repeats are start date plus n times the interval in civil days.

Boundary

This is civil-date planning arithmetic, not a public-holiday, payroll, legal deadline or live timezone database.

Source basis

Browser Date objects and ISO-style HTML date inputs supply the factual layer.
