ICS Timezone Fixer

Welcome! This free tool helps you fix timezone issues in .ics calendar files (such as those from Outlook or Office365) so that Google Calendar and other apps display your event times correctly.

How to use:

Find the public URL to your .ics calendar file (it must start with https://).
Paste it as a query parameter named ics_url in this app's address bar.
Example usage:

Example:
https://your-server.com/?ics_url=https://original-calendar-url.ics

Use the new link as a replacement for the original one in your calendar app.

Note: This tool does not store or log your calendar data. All processing happens live, and your data is never saved.
If you need reliable access, you can download and run this app on your own server using the open-source code.
