This ought to be easy.

It should be 21 March, June, September, December but it's not. They can shift by a day depending on what year it is. The leap year recorrects it all but things get more upset over the 4 years between them but never more than a day out for each.

To be honest, I understand how this works but I just use the 21 of Mar, Jun, Sept, Dec anyway. It makes little difference.

Other dates are more sensetive.

Easter depends on the moon.

Vernal Equinix, Full moon, Sunday

Vernal equinox is 21 march...first day of spring
Full moon is the date of the first full moon after 21 March
Easter is on the Sunday followijg that full moon.

This can give a shift of over a month as to when Easter occurs. Quite bizaar considering it's the most important day in a religious calander

Autumn started today, March 1
Winter June 1
Spring September 1
Summer December 1

It is the same every year. Some countries start on the solstices and equinoces which is silly, it makes calculating seasonal statistics difficult. The idea of four seasons is human artefact so you can start them whenever is convenient.

We don't have four seasons in Australia, certainly not four seasons of three months' duration each but we go along with the northern European designations for convenience. We do, however, start them on sensible dates.

Just in case....what? *puzzled look*

They're pretty much the same every year...around the 21st of the month of March, June, Sept, and Dec.

You can look it up online to be sure. It may fall on the 22nd sometimes, esp due to leap years.
