Plain-English RRULE builder
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.
Edit the words later, not the syntax. Calfeed regenerates the rule for you.
Example
Every Tuesday and Thursday until July 31, except the week of July 4.
Becomes
Recurring rule plus an exclusion for June 30 and July 2.
