###  Need to test your iCalendar feeds?

The [ iCalendar Validator ](/validator.html) provides developers and testers a
method to validate their iCalendar feeds, which can take data from either a
URL, file or text snippet and compare it against the [ RFC 5545 specification

best iCalendar validation tools available on the internet. More information
about the validator can be [ found here ](/More-Info/about-the-icalendar-
