When is the first day of Spring?

Today, Wednesday 1st March or Monday 21st March?

The answer is both.

The astronomical Spring Equinox is Monday 21st March. Based on the lunar cycles this is the traditional way of establishing the official dates for the seasons.

The National Centers for Environmental Information (NCEI) introduced meteorological seasons because traditional seasons varied in length from 89 to 93 days and it was difficult for experts to compare statistics from one year to another.

Meteorological spring is considered to encompass the months of March, April and May. The other meteorological seasons each also consist of three consecutive months:

Meteorological winter comprises December, January, February.

Meteorological summer comprises June, July, August.

Meteorological fall comprises September, October, November.

At Resin Master we watch the weather very carefully to ensure our work schedule can work around cold and wet periods that are not suitable for resin laying.
