Question on Time

[Elliott]

I was observing that there are two common measures by which we measure the start of a new day. One is at midnight when the new day literally begins, and the other is when we wake up in the morning to begin the new day. I was thinking that different religions or civilizations in history may have their own measure of the start of a new day and was wondering if anyone had any insight on the matter.

In Jewish culture, the "day" begins at sundown.

I assume it was the same in Celtic culture, but I don't know. At least, the year begins with winter (Samhain).

In ancient Rome the day began at sunrise and time was counted in flexible hours from sunrise being the first hour of a 24 hour day

Sunrise to sunset were the were the first 12 hours, sunset to sunrise the second 12 hours. So hours were longer during the summer.


They had an 8 day week until Constantine adopted the 7 day week with Sunday being the first day of the week

They may have adopted that from the Egyptians. They had clepsydra that could be adjusted, depending on the month, to always divide the day and the night into twelve hours.

So their year would begin around October?

I always wondered if there were civilizations that had a different measure of a week. That is really interesting.

I believe it was something to do with rhe Greeks but i never followed it up.

Around November. The idea of Samhain being the 31st of October comes from one Roman source, but is most likely a misinterpretation. The Romans had a solar calendar, while the Celts had a lunar calendar. There is a fragment of a Celtic calendar, recorded by Romans, the Coligny Calendar. It records a 19-year calendar with 12 and 13 months years. New year may have been something like "the second new moon after the equinox". But that is just my assumption based on the idea that they were consistent in their timekeeping. We know that the year began with the dark time (winter) and maybe the month and the day may have had a similar idea (new moon and sundown).

The length of a week (if there was a unit between day and month), was all over the place. 7, 8, 10 and 12 being used through various cultures. And sometimes they weren't fixed. A 7-day week gives you roughly a quarter of a lunar month, but to keep in sync, sometimes days were added that didn't belong to any week, mostly holy days. The same was done with solar years. Iirc, the Romans before Julius Caesar had 360-day years (12 months with 30 days each), with a 5-day feast that was "between the years".

October 31?! How timely this conversation is.

October 31?! How timely this conversation is.

Christians have invented a lot of Holy Days over the centuries and some were strategically put at the same (or around a) day, where a pagan feast was. All Saint's Day (aka Allhallows) was put on November 1st to coincide with (presumed) Samhain. The Day before became Allhallows Eve, later Halloween. So it has a veneer (and name) of Christianity, while the rites remained based on paganism.
Similar applies to Christmas, which is an appropriation of the Roman Saturnalia.
Easter, on the other hand, is a genuine Christian holy day, where pagan rituals were later added to it.
All genuine Christian, biblical holy days are floating holidays, as they go back to the Jewish lunar calendar, i.e. Good Friday, Easter, Ascension, Pentecost (and Ash Wednesday). All others are later inventions, when Christianity had adapted the Roman solar calendar.

Does anyone else have any insight they'd wish to share on this matter?
