Place links near your main CTA and repeat them once near the footer
Test both HTML and plain-text versions to ensure links stay clickable

Add buttons to your website

Replace each href with the generated URLs you created above.

<!-- Replace the href values with generated links -->
<div style="display:flex;gap:8px;flex-wrap:wrap">
  <a href="https://calendar.google.com/..." target="_blank" rel="noopener noreferrer" style="padding:10px 14px;border:1px solid #e5e7eb;border-radius:8px;text-decoration:none">Add to Google</a>
  <a href="https://outlook.live.com/calendar/0/deeplink/compose?..." target="_blank" rel="noopener noreferrer" style="padding:10px 14px;border:1px solid #e5e7eb;border-radius:8px;text-decoration:none">Add to Outlook</a>
  <a href="https://outlook.office.com/calendar/0/deeplink/compose?..." target="_blank" rel="noopener noreferrer" style="padding:10px 14px;border:1px solid #e5e7eb;border-radius:8px;text-decoration:none">Add to Office365</a>
  <a href="https://calendar.yahoo.com/?v=60&..." target="_blank" rel="noopener noreferrer" style="padding:10px 14px;border:1px solid #e5e7eb;border-radius:8px;text-decoration:none">Add to Yahoo</a>
  <a href="data:text/calendar;charset=utf8,BEGIN:VCALENDAR..." download="event.ics" style="padding:10px 14px;border:1px solid #e5e7eb;border-radius:8px;text-decoration:none">Download ICS</a>
</div>

Note: For RRULE (recurring) events, Outlook/Office365 URLs may not fully support it. Prefer ICS for Microsoft calendars.

Website best practices

Show button labels for each calendar (Google / Outlook / Office 365 / Yahoo / ICS)
Use responsive styles so buttons wrap on mobile without shifting layout
Add rel="noopener noreferrer" to external links for security

What is a calendar registration URL?

A calendar registration URL lets anyone add an event to their calendar with one click, without creating an account.

Unlike public calendars, these links are purpose-built for one event and keep the details consistent across Google, Outlook, Yahoo, and ICS.

Where to use it

Email: add calendar buttons next to your main call-to-action.
Website: place buttons on landing pages, event pages, or blogs.
Social: include a calendar link in posts or link-in-bio tools.

Frequently Asked Questions

Do you support recurring events (RRULE)?

Yes. Google Calendar and ICS support RRULE. Outlook and Office 365 have limitations; for recurring events, we recommend using the ICS option.

What’s different between Google and Outlook calendars?

Google Calendar generally handles add-via-URL and RRULE better. Outlook/Office365 links may not fully support recurring events; provide an ICS file for best compatibility.

What is an ICS file?

ICS is the iCalendar file format, readable by most calendar apps (Google, Apple, Outlook). You can attach or link it for users to import the event reliably.

Which calendar apps are supported?

We support Google Calendar, Outlook, Yahoo Calendar, Apple Calendar (iCal), Office 365, AOL, and any app that supports ICS files.

How many links can I create for free?

This tool is completely free with unlimited usage. No account or registration required.

What's the difference between this tool and Calen?

This tool generates simple calendar links. Calen provides beautiful event pages, attendee management, email notifications, analytics, and everything you need to grow your event audience.
