Calendar-specific formats
Use the output the provider expects
There is no single web URL format shared by every calendar. Offer the relevant direct links and keep ICS available as the interoperable file option.
Outlook and Microsoft 365
Outlook.com and Microsoft 365 use separate web hosts. For Outlook desktop, include the ICS file rather than relying only on a web link.
Generate Outlook links →Apple Calendar
Apple does not publish a web compose URL. A downloadable ICS file is the correct event format for Apple Calendar on iPhone, iPad and Mac.
Generate an Apple Calendar ICS →Yahoo Calendar
A calendar.yahoo.com URL can carry the title, timing, location and description into a new Yahoo Calendar event.
Generate a Yahoo Calendar link →Link, button or widget
Choose how the calendar action appears
Use direct provider links in email, an Add to Calendar button on a page that already explains the event, or a compact iframe when the embedded card also needs to show the event context.
Before you publish
- ✓Confirm start and end values, including all-day behavior.
- ✓Use an IANA timezone instead of a short abbreviation.
- ✓Test every provider link and the downloaded ICS file.
- ✓Keep the visible event copy consistent with the calendar entry.
Adding events to calendars FAQ
How do I add an event to Google Calendar for Gmail users?
Create a Google Calendar event link. Gmail does not use a separate calendar format; Gmail and Google Workspace users add events through Google Calendar.
How do I add an event to Apple Calendar?
Create and share an ICS file. Apple Calendar imports the standard ICS event format on iPhone, iPad and Mac instead of using a public web create-event link.
Should I include a timezone in a calendar link?
Yes. Use an explicit IANA timezone such as Europe/Madrid or America/New_York so the calendar provider can show the correct local time and handle daylight-saving rules.
Will a generated calendar event update after a guest adds it?
No. A one-time provider link or ICS import creates an independent event in the guest calendar. Use a subscription calendar when followers need future additions and changes to sync through a feed.
