Generate a standards-ish .ics calendar event locally. No accounts. No tracking. No server calls.

Tip: use IANA TZ names. If unsure, keep UTC.
If Bulk mode has any rows, single-event fields above are ignored. Dates can be YYYY-MM-DD (all-day) or YYYY-MM-DDTHH:MM. Optional rrule is pasted verbatim (e.g. FREQ=WEEKLY;INTERVAL=1;BYDAY=MO,WE,FR).

Notes: this emits a simple VEVENT with DTSTART/DTEND, UID, and DTSTAMP. Some calendar apps handle TZ rules differently; if you need absolute times, use UTC.

Sanity checks: opens in Google Calendar/Apple Calendar; file is plain text; no external references.

Privacy: don’t paste secrets into calendar descriptions if you plan to forward invites.
