Editing meeting times on club website calendar

The meeting times on the club calendar on our website are incorrect for November and December 2015 and for January, February, and March 4 & 11. The time should be 12:00 noon but is 11:00 a.m. I did not post those times and cannot figure out how to edit. When I try to make a change, the agenda for that date opens. How do I change the incorrect time on the dates listed above. All our other meetings are listed correctly at 12 noon.
Thanks,

It must be a daylight savings thing... I will let one of the developers of this chime in...

Just open those agendas, click the pencil button to edit, then click save, and the corresponding calendar entries should get corrected.

Thanks! It worked like a charm!
