thank you for your reply....I did check the ACT! calendar - and those time zones are accurate.   I was wondering about the settings in hebcal GMT zones - I noticed Chicago is listed in Zone 5 - but it really is in Zone 6---could that have anything to do with this??

I have not left home in months - so my time zones are steady- and when I did the download of the calendar - it did not ask for a time zone...

would you be willing to revisit my request given this information?

thank you!
