Recurring Date Generator (RRULE)

What is RRULE?

RFC 5545 recurrence rules power calendar subscriptions everywhere. This tool builds a valid RRULE from a form and previews upcoming dates.

How it works

The form composes the FREQ, INTERVAL, COUNT/UNTIL, BYDAY and BYMONTH fields into a standard RRULE string; the preview computes the next occurrences locally.

1. Enter your input. Type or paste your input into the field above — the tool responds instantly.
2. Review the result. Output updates live as you type. Everything runs entirely in your browser.
3. Copy or download. Use the Copy button to grab the result, or Download to save it as a file.
