I was born in Latvia, Riga city in Soviet Union times. In that period our time zone was Moscow time zone. Now we use our real local time and difference is -1 hour. I would like to now what time I should use to calculate my Ba Zi chart. My birth date is 26.09.69. and birth time is 21.20 using Moscow time. The same question I have about summer light saving time. Thank you for answer.
