If we cannot recite Kiddush in the 6th hour because it has a bad mazal,
then we also cannot get married in the 6th hour because it has a bad mazal,
and we also cannot pray in the 6th hour because it has a bad mazal,
and we also cannot conduct business in the 6th hour because it has a bad mazal,
and we also cannot learn Torah in the 6th hour because it has a bad mazal.
==============================================
“… every hour one of the seven mazalos, rules:
Mercury, Venus, Earth, Mars, Jupiter, Saturn and Neptune…”
This is Astrology, which is a false superstition copied from non-Jews.
Believing in Astrology is like believing in Santa Claus.
Waiting during the 6th hour on Friday night is like waiting for Santa Claus.to come on Xmas.
This minhag is disgraceful, and should have been prohibited many centuries ago.
