If you need different versions of IE, this is a great program to test with.

Great, thanks for the tip Scott

Clive,

You can also visit a couple of different websites that will provide screen shots of your pages using MANY different browser/os combinations. One I have used is http://www.browsercam.com/Default2.aspx it will take a while, but it shows some interesting interactions with the different browsers.

I came up with a workaround that I've implemented that fixes the problem. Essentially, I have 2 calendar html pages. When you click on the calendar link (calendar.html) the first page loads (sometimes with corrupted data) but the first page immediately redirects to calendar2.html which is identical to calendar.html without the redirect meta tag. This simulates a single refresh.

Meta tag for redirect in calendar.html:

<meta http-equiv="refresh" content="1;url=http://www.thebigwheelsband.com/calendar2.html">

You can see this in action at:

Johnny,

Did you put this in the tricks and tips for the calendar?

Hey everyone!

I added an article to the CoffeeCup knowledgebase that details this workaround. You can check it out here: http://www.coffeecup.com/help/articles/my-calendar-displays-incorrect-dates/

Thanks for your input, Johnny! If you want a shout-out in the article, let me know

Sure, a little shout-out never hurts - glad I could help.

I have a similiar issue although mine may be a bit more challenging as my calendar is embedded on the site home page and not on a sub-page where I could use a refresh.

http://www.hollistonagcom.org/ and our calendar will draw with all days in the dark blue (indicating an event).

I've seen this on IE, FF and Safari but less on Safari than the others.

William, it seems Johnny's example is more than just the calendar itself, so it'd be the same if you refreshed your entire index page. I suppose you could throw the calendar into an iframe so it'd blend in just as it does now, only you could then have only the calendar refresh adding the meta tag to the calendar's html file.
