Hi diallists
As you'll probably know, in some countries
there is a folklore-based calendar
that overlaps the legal one and in which seasons
begin about six weeks before, ie.,
halfway between the equinox and the solstice
(Candlemass, Imbolic and all these
festivals all over Europe...).
Does anybody know if there is somewhere a
Sun's elevation-based calendar like this one:
* Winter: the elevation of the sun at
noon is lower than (Latitude - 23.45 / 2) deg
* Summer: the elevation of the sun at
noon is higher than (Latitude + 23.45 / 2) deg
* Autumn and Spring: between the
former.
I think this is quite an empirical calendar whose
only problem is that Summer and Winter
are almost double length than Autumn and Spring
(look at any declination-vs-day curve), but
IMHO it gives a good idea of which are hot and cold
seasons.
