    .ics file or add-to-calendar link?

    An .ics file works with every calendar, keeps reminders and repeat rules, and can be attached to an email, newsletter or website ("Download the event"). Add-to-calendar links open Google Calendar, Outlook.com, Microsoft 365 or Yahoo with the event pre-filled, which is the fastest option for people using those web calendars; you can paste the copied Google link into a chat or email. Many organizers offer both. To check what time an event will be for people elsewhere, use the Time Zone Converter.

    Frequently asked questions

    What is an .ics file?

    An .ics file is a calendar event in the iCalendar format (RFC 5545), the open standard used by Outlook, Apple Calendar, Google Calendar, Thunderbird and phones. Opening or importing the file adds the event, with its time, location, description, reminders and repeat rule, to your calendar.

    How do I add an .ics file to Google Calendar?

    On a computer, open Google Calendar, click the gear icon > Settings > Import & export, choose the .ics file and the calendar to add it to, then click Import. Or simply use the Google Calendar button on this page, which opens the event ready to save.

    How are time zones handled?

    The event is written with the time zone you choose (for example America/New_York) together with a VTIMEZONE block describing that zone's daylight saving rules, so a 10:00 meeting stays at 10:00 local time all year, even for repeating events. Each attendee's calendar shows it in their own time. You can also choose to write the times in UTC.

    Can I create a recurring event?

    Yes. Choose daily, weekly (on any days), monthly (on a day number or on, say, the second Tuesday) or yearly, an interval such as every 2 weeks, and whether it ends after a number of times or on a date. This becomes the event's RRULE.

    Will reminders work in every calendar?

    Reminders are saved as VALARM entries, which Outlook, Apple Calendar and Thunderbird honor. Google Calendar ignores reminders inside imported files and uses your default notification settings instead.

    Why does an all-day event end on the next day in the file?

    In the iCalendar standard the end date of an all-day event is exclusive. A one-day event on 5 March is stored as starting 5 March and ending 6 March, which every calendar displays as a single day.

    Is my event data stored anywhere?

    No. The .ics file and links are generated in your browser. Nothing is uploaded, and the add-to-calendar links only send the event details to the calendar service you choose to open.
