Add to calendar.
Fill in an event once and get a correct .ics download plus Google, Outlook, and Yahoo quick-add links — recurrence included where each provider actually supports it. Or paste a whole list of events and get one combined .ics back, free.
Event
.ics files and Google / Outlook / Yahoo links for one event (with recurrence) or a pasted list of events.
Bulk .ics export
One event per line: title, start, end, location, description with start and end as 2026-10-01T09:00. Every valid line becomes one entry in a single .ics file.
Result
Fill in the event and press Generate.
How it works
- The .ics download is the only reliably correct way to hand a recurring event to Apple Calendar, Outlook desktop, or any calendar app — it carries a real RFC 5545
RRULE. - Google Calendar's quick-add link also supports recurrence (
recur=RRULE:...), so its link reflects your full repeat rule. - Outlook.com and Yahoo quick-add links have no recurrence parameter in their URL schemes — their links always create a single, one-time event even if you set a repeat above. This is the specific thing most add-to-calendar generators get wrong by silently dropping the recurrence instead of saying so.
- On-device: everything is generated in your browser. No event data is sent anywhere.
Worked example
Create a weekly team meeting that starts on Monday 2026-11-02 at 09:00 and repeats for 10 occurrences. The .ics file carries RRULE:FREQ=WEEKLY;COUNT=10, so Apple Calendar and Outlook desktop show ten Monday meetings, the last on 2027-01-04. The Google Calendar link carries the same rule. The Outlook.com and Yahoo links create only the first meeting on 2026-11-02, because their link formats take no repeat rule. RFC 5545 gives the same rule syntax in its own example, FREQ=DAILY;COUNT=10;INTERVAL=2, ten occurrences every other day.
Sources and as-of date
Retrieved 2026-10-26: RFC 5545, Internet Calendaring and Scheduling Core Object Specification (iCalendar), section 3.3.10 on recurrence rules (re-read). The behaviour of the Google, Outlook.com and Yahoo quick-add links is not specified in a vendor document we could cite, so check a link in your own calendar before relying on its repeat handling.
Included
The single-event generator with daily / weekly / monthly / yearly recurrence, end dates and occurrence counts, plus the bulk box that turns a pasted list of events into one combined .ics file.
Frequently asked questions
What is an .ics file?
A calendar file in the iCalendar format defined by RFC 5545. Most calendar apps import it, including repeat rules.
Why does my Outlook.com link create only one event?
Those links take a single event and no repeat rule. Download the .ics file to keep the recurrence.
How do I set an event to repeat 10 times?
Choose a repeat pattern and an occurrence count. The file gets a rule such as FREQ=WEEKLY;COUNT=10.
Is my event uploaded anywhere?
No. The links and file are generated in your browser.
