Note: We are aware that this calendar is broken for many of you. Unfortunately, this is due to a security change made to most browsers within the last few months, and Charms must fix their calendar to be displayed here. They have thus far been unwilling to make fixing this a priority despite our requests.
Workarounds include:
Technical/nerdy information about this problem for any curious minds: Most browsers began enforcing the SameSite cookie attributes to prevent Cross Site Request Forgery, or CSRF attacks. If a site uses SameSite cookie attributes (which they should), they must set the attribute properly. If you have set the SameSite attribute to 'None', so it can be loaded on a third party site, you must also set it to be 'Secure'. Charms sets a cookie when the iFrame loads with the school code. This cookie has a SameSite attribute of None, but is not set to Secure, which means that the cookie is rejected by any browser with that policy. Firefox is only warning about it at this time. Chrome and Safari are enforcing the policy, so you get the login page on those browsers.

Workarounds include:
- So far the Firefox browser has not started enforcing this change. Firefox will work until they do. They could start at any time.
- You can go directly to the Charms web page, and log in using school code 'americanforkhsb', then navigate to the calendar.
- You can still sync the calendar with your phone or google calendar.
