BeerSmith said:I found the problem - November 4th just happens to be the day that we "leap forward" this year for daylight savings time. Apparently the change of clocks is throwing the calculation off by a day at that point. It shows up on my calendar (West coast) but may have smaller effect for others.
The good news is that it is a very easy thing to fix - I'll post a patch shortly. Also it only affects that month and does not affect any of the others (i.e. December).
Cheers,
