Does this tool send my event details to a server?

No. Every link and the .ics file are built entirely in your browser using JavaScript — nothing you type is sent, logged, or stored anywhere. Refreshing the page clears everything.

Why is there no "Add to Apple Calendar" link, just a download button?

Apple never published a public web URL format for adding events to Apple Calendar the way Google, Outlook, and Yahoo have. Apple Calendar (and most desktop calendar apps) instead opens .ics files directly, so downloading the generated .ics file and opening it is the standard way to add an event to Apple Calendar.

What is an .ics file?

An .ics file is a plain-text calendar file in the iCalendar format (RFC 5545). It is a universal standard understood by Apple Calendar, Outlook desktop, Google Calendar (via import), Thunderbird, and virtually every calendar app, which is why it is the most reliable "works everywhere" option.

How do timezones work for the event I create?

Enter the date and time exactly as they should appear in the timezone you select — the tool converts that local time to the correct UTC instant for the Google, Outlook, and Yahoo links, and embeds the timezone directly in the .ics file so calendar apps display the right local time for anyone who opens it, wherever they are.

Can I create an all-day or multi-day event?

Yes — toggle "All-day event" and just pick a start and end date (no times needed). A one-day event uses the same start and end date; for a multi-day event, set the end date to the last day the event should show as active.

Can I use the generated .ics file or links in a marketing email or event page?

Yes. The Google, Outlook, and Yahoo links are plain URLs you can paste behind a button in any email or webpage, and the .ics file can be attached to an email or linked as a direct download — this is exactly how webinar invites, wedding websites, and event confirmation emails add "add to calendar" buttons.
