* When I run our site through the W3 validator, it fails compliance due to several
calendar-related issues. Are there any plans to address this in future releases?

* What issues in particular?
Anyway, no, not in 2.2, unless it’s something which
has a big impact.can you try also with twenty fourteen theme?

* Hi,
* Sorry for the wait. I did try the twenty fifteen theme as a test and the calendar
validated to HTML5. Thanks for the help troubleshooting.
