There will be local customs but the technical time, taken from the Latin
description of the hours is that Italian hours were counted from sunset and
Babylonian hours from sunrise. There is no mention of dusk

Hi Sara, Ross et al,
My understanding is that a seasonal (or unequal) hour is a period of time ('in
the first hour' etc) and not an instant. It is never

Hi diallists,
This is not a sundial problem, but a time discrepancy I don't understand
between NOAA sunrise calculations and the results of two reliable planetarium

Thank you for that reminder, Frank!
I will be the first to say that it made me learn something.
I live in France, but I can tell you that no one, in a quick survey of a half
dozen people, could explain what, literally, "bissextile" actually refers to in

A dialist in Australia explained that the school argued that the children would
be tempted to spend too much time in the sun because of the dial.
In another part of this discussion, perhaps in the UK, someone mentioned that

I completely agree with you. I want to correct something though.

Thanks for pointing out the truth, Tony!
I smelled something fishy about the website, given conservative Christians'
penchant for overreacting to the merest hint of a slight, and I couldn't find
anything on the BBC website about it.
Thanks for the link. It won't stop the lies being propagated

Hi Brent,
It is only a coincidence that the full moon/ lunar
opposition happened so close to the equinox this year, AD 2010. It could
happen any of the 14.5 days around the equinox, so roughly September 5
to October 5.
Last year the closest lunar opposition to the equinox was October 2 (or 3

The Bible has a miracle-story concerning the reversal of a shadow on a
sundial, but it doesn't seem to have any suitable quotes (at least in
Latin).
See Isaiah 38:4-8 and 2 Kings 20:1-11.
The first one, in the King James Version, contains a nice line if you

Combining an astronomy hobby with sundials, I wonder if anyone has thought
of how a sundial on Mars or Venus might look (ignoring the thick venusian
clouds for the experiment), or one on the Moon?
And what about designing dials for Earth that keep the different planetary
