How to Create an .ics Calendar File by Hand
An .ics file is just structured text with a start, an end, and a summary. This guide shows the lines that matter and how to keep times readable.
What is the Calendar Event File Generator?
An .ics file lets someone add your event to their calendar with one import, instead of retyping every detail. This tool converts a title, date, start and end times, location, and notes into that standard calendar text. Save it with an .ics ending and it can be opened by most calendar apps.
How to use it
- Enter the event title and date.
- Add start and end times, location, and notes.
- Click Generate Calendar File.
- Save the text as event.ics and import it into a calendar.
Worked example
For a Team Meeting on 2026-11-05 from 10:00 to 11:00, the tool returns an .ics block with DTSTART:20261105T100000 and DTEND:20261105T110000.
What is inside an .ics file?
A calendar wrapper, an event block, a unique id, start and end stamps in basic date-time format, and the summary, location, and description of the event.
Frequently asked questions
Do times include a timezone?
This simple file uses plain local times, so check the imported event if guests are in other zones.
Can I send the .ics file by email?
Yes. Attach it like any file and most recipients can add it with one tap.
