Using the attached project, I could not replicate the issue in my environment. Using the described steps, I have change the month to March 2010 and try to replicate the error in Agenda view, Month view, and Timeline view without any success.

Did you use non-US culture in your environment?

Hi,

We are using en-GB CultureInfo string, it happens in both en-GB and en-US.

Thank you for the video, however I still could not replicate the issue using the live sample you shown in the video. I have asked my colleague's help to try to replicate the issue as well, however none of them successfully replicate the issue.

I have discussed this issue with the developer and they could not replicate the issue as well, our suggestion is please try to clear you browser cache in order to remove any previous version cached javascript.  

Update: 

The developer also suggest if the suggestion does not solve the issue please provide us with a virtual pc with your configuration so we could replicate the issue in our environment.

Hi,

I have removed the cache and ran the demo again and the javascript error is happening.

Also I checked the intersoft's live demo page in Firfox. Please check the attached image.

It happens when you are in the first quarter. By default that demo shows you the first quarter and it straightaway throws that javascript error.

Please check the attached image.

Further analysis of the issue has enabled our developer to discover the cause of this issue. It seems under GMT -5 Timezone, the issue you reported will occur. The issue occurs because the event has passed the Daylight Saving for that timezone.

A fix has been aplied in our nightly build, which could be retrieved here
