I have to admit that until I read what you wrote and did some checking
that I was under the impression the Babylonian hour was a fixed hour of
60 minutes like the one we have today. <br><br>
The following is from

</a></b></font><font size=3>Once both the light and dark hours were
divided into 12 parts, the concept of a 24-hour day was in place. The
concept of fixed-length hours, however, did not originate until the
Hellenistic period, when Greek astronomers began using such a system for
their theoretical calculations. Hipparchus, whose work primarily took
place between 147 and 127 B.C., proposed dividing the day into 24
equinoctial hours, based on the 12 hours of daylight and 12 hours of
darkness observed on equinox days. Despite this suggestion, lay people
continued to use seasonally varying hours for many centuries. (Hours of
fixed length became commonplace only after mechanical clocks first
appeared in Europe during the 14th century.) <br><br>
thank you for making me aware of this.<br><br>
