Calendar Event Link Generator
Build "Add to Calendar" links for Google, Outlook, Office 365 and Yahoo, plus a downloadable .ics file.
How it works
Fill in the event details once and this generator builds a ready-to-share
“Add to Calendar” link for Google Calendar, Outlook.com, Office 365 and
Yahoo Calendar, plus a downloadable .ics file that works with Apple Calendar,
Thunderbird and anything else that speaks iCalendar. Paste the link into an email, a landing
page, a newsletter or a webinar confirmation and one click drops the event straight into your
reader’s calendar — no typing, no time-zone mistakes, far fewer no-shows.
Pick the time zone the event actually happens in and every link is converted to UTC
(20260915T090000Z), which is the one format every calendar provider agrees on, so
an invitee in Tokyo sees the correct local time automatically. Daylight-saving is resolved from
the IANA time-zone database built into your browser, using the offset in effect on the event
date. Tick All-day event for conferences or holidays and the end date is written as the
exclusive next-day boundary the iCalendar spec requires. Everything is assembled by plain
JavaScript on your device — no upload, no tracking pixel, no sign-up and no ads.
Frequently asked questions
How do I create an "Add to Calendar" link for an email?
Fill in the event title, date, time and time zone above, then copy the Google Calendar, Outlook.com, Office 365 or Yahoo link and paste it behind a button or text link in your email. Because the link points straight at the calendar provider, one click opens a pre-filled event your reader just has to save. The HTML snippet gives you all four links at once, ready to paste into a newsletter template or landing page.
Which calendars do these links work with?
The generated URLs cover Google Calendar, Outlook.com, Microsoft 365 (Outlook Web) and Yahoo Calendar. Apple Calendar, Thunderbird and most desktop and mobile clients do not accept a web link, so use the Download .ics button for them — the iCalendar file it produces opens in any app that supports the .ics standard, including Apple Calendar on iPhone and Mac.
How are time zones and daylight saving handled?
Pick the time zone the event actually takes place in and every link is converted to UTC (for example 20260915T090000Z), the one format all providers agree on, so invitees anywhere see the correct local time. The offset is looked up in the IANA time-zone database built into your browser for the exact event date, so summer and winter time are resolved correctly even for events months away. All-day events are written as plain dates with an exclusive end date, exactly as the iCalendar spec requires.
