Plain-English RRULE Generator
Skip the RRULE syntax. Describe the pattern in words.
RRULE is the recurring-event format every calendar app understands. It is also dense. "FREQ=WEEKLY;BYDAY=TU,TH;UNTIL=20260731T000000Z" is what "every Tuesday and Thursday until July 31" actually compiles to.
Calfeed lets you stay on the left side of that equal sign. Describe the repeat the way it shows up in your head. Calfeed builds the rule and adds the events. For free-form schedules with mixed recurrence, the plain-text to calendar tool handles it end to end.
Edit the words later, not the syntax. Calfeed regenerates the rule for you. See when to edit vs publish a new calendar for the rule of thumb across seasons.
Example
Every Tuesday and Thursday until July 31, except the week of July 4.
