Why are birthdays appearing over a two day period?

[Keith in Brooklyn]

I notice that the birthdays on my calendar that fall in daylight savings time
fall over two days. Upon further review, I see that they go from 1am one day
to 1am the next day, thus the dates appear on two consecutive days. I
checked and I'm in the right time zone. Can anyone help?

Did you also check the daylight saving time setting in both Windows clock
and in Outlook's Calendar?
