Many people have asked questions about whether Daylight Savings Time (DST) should be accounted for when setting a person's birth hour. So I asked an expert to answer. Dr. Heiner Fruehauf wrote

I most definitely recommend offsetting for daylight savings time (as it is a "political" time that has nothing to do with the real cycles of the universe).

That explaination makes perfect sense to me. The Universe isn't subject to "political whims" when considering cyclical time over thousands of years. Heck, DST has only been around since invented by Benjamin Franklin in 1784, a mere 235 years ago. In fact most countries and states only adopted DST after 1970.

So, thank you Dr. Fruehauf for answering this important question. YES! Remove the "DST" adjustment if born in the summer time to get the correct time of birth!
