Create a standard iCalendar (.ics) event file in your browser. Add a title, all-day or timed dates, location, description, link and a reminder note, choose floating local time or UTC, preview the event and the raw file, then copy or download the .ics.
Calendar Event Generator creates a single-event iCalendar (.ics) file that many calendar apps can import. Enter a title, choose an all-day or timed event, set the start and end, and optionally add a location, description, web link and a reminder note. The file includes VERSION, PRODID, a randomly generated UID, a DTSTAMP and valid DTSTART and DTEND values, uses CRLF line endings, escapes special characters and folds long lines without splitting UTF-8 characters.
Timed events use floating local time by default: 09:30 stays 09:30 in whatever time zone the importing device uses. You can instead convert the times to UTC using this device’s time zone, which fixes the moment in time. The reminder note is added to the description as text only; no alarm is created. Nothing is sent to any calendar, and the event is not added automatically — you open or import the file yourself. Calendar apps differ, so check the event after importing.
A time without a time zone, such as 09:30. Calendar apps show it at 09:30 in the time zone of the device that imports it, so people in different time zones see the same clock time rather than the same moment.
When the event happens at one fixed moment for everyone, such as an online meeting. The tool converts your entered time from this device’s time zone to UTC, and each calendar then shows it in its own local time.
No. The reminder note is added to the event description as text only. Set any alarms in your calendar app after importing.
As dates only. iCalendar uses an end date that is the day after the last day, so a one-day event on 5 March has DTEND of 6 March.
The file follows the iCalendar standard, but calendar apps differ in what they import and how they display it. Check the event after importing.
No. The tool only creates a file. Open or import it in your calendar app yourself.
No. Everything runs in your browser. Times, laps, shifts, events and dates are not uploaded and are not saved in browser storage. Reset clears them, and closing the page discards them.
