sunrise and sunset times

[Merrilyn Serong <>]

Hi all
As there has been a discussion of tides, I thought that a discussion of
sunrise and sunset times might be just as appropriate.

I have been recording sunrise and sunset times from the newspaper for
Victoria during spring and summer.  In the weeks prior to the longest
day (summer solstice, 21 or 22 Dec) the daylight hours (or photoperiod)
of any given day begin and end earlier by the clock than on a day with
the same number of daylight hours (same length photoperiod) that falls
the same number of days after the summer solstice that the given day
does before the solstice.  I hope that sentence is clear.
Does anybody know why this is so?

Thanks very much,
Merrilyn.
