Astronomically spring starts at the Vernal equinox on the 20th.
Below is a March double page from Edith Holden's Diary of an Edwardian Lady .
In the Roman calendar March,or Martius, was the first month of a new year. The month was named after Mars, the god of war and the guardian of agriculture. March was the month when both farming and warfare could begin again after winter.
The Saxons called it Lentmonat, or lengthening month, because of the equinox and lengthening of days and this is the origin of the word Lent. By the end of the month there will be two extra hours of daylight and we change clocks to BST on the 29th.
The March full moon on the 9th was known as the plough moon, wind moon or Lentern moon.
The 21st is St Benedicts Day and has this old prophesy ..............
Whatever the weather on 21st that weather will stay until 21st June
There are many other weather sayings, the best known is
March winds and April showers
Bring forth May flowers.
Also.....................March month of many weathers
Dry days are precious to get seeds sown.................A peck of dust in March is worth a king's ransom
And on the same theme.................A dry March never begs it's bread
I hope there is a morning when, like Robert Browning we can say
The year's at the spring,
And day's at the morn;
Morning's at seven;
The hill-side's dew-pearl'd;
The lark's on the wing;
The snail's on the thorn;
God's in His heaven -
All's right with the world!
