the length of this day, 19 march [annually] is 12 twelve hours and 4 four minutes- near the date when day and night have equal lengths. today's length is 2 minutes more than yesterday's length as the day's length increases.
in israel march 16 is the technical equinox

[therefore spring has arrived this in contrast to the "equinox" which is the 21 of march as we were taught in school and the average balance as explained in footnote]
each year has a cycle of short days and then longer days and back to short days coinciding with a cycle of cold days and hotter days and then cold days the cycles are almost parallel and the seasons are divided by the phases related to the length of the day- winter begins on the shortest day and as the days get longer the when the lengths of day and night are equal begins spring
until the longest day beginning summer as the length of the days becomes smaller until the second equinox when the length of the day and night are equal in israel september 26 annualy and that marks autumn until the shortest day completing the annual cycle.
so although hot days and cold days were meixed this month it is time for a song about swimming in the outdoor pool after applying SUNBLOCK LOTION for your safety.

:
the weather is warm, so let's go swimmin'!
go get your swimwear, you men and women!
i need to clean the stuff on the water
my parents pay fair 'cuz I'm their daughter
my parent's great pool has room for plenty
I'll invite my whole class or just 20!
dad told me I must invite them all soon!
they should come swim tomorrow afternoon!
last time some of them acted obnoxious
and the thought of dour nate makes me nauseous
but most were good and larry made me laugh
I will only invite exactly half!
**footnote different places have differing dates for the equinox and the average balance is the 21 for example in israel there is a 5 day difference 26-21=21-16 so the balance is 21 and the same in other countries to the north and south which have differing dates of technical equinox [therefore the simple definition of equinox is taught as the 21 of march and september]
