Spring Equinox 2020:

The Earliest First Day of Spring in 124 Years!

When is the first day of spring?

I don’t know about you but I am already smelling that fresh spring smell of new plants and blooms when I walk in the morning, and the sun is feeling soooooo good to me. This morning I had a spontaneous pajama-gardening moment in the front yard, which led me to plan my new herb garden – and then I wondered, am I springing too early? So I looked up when the first day of spring equinox is and wow, was I in tune!

On Thursday March 19, 2020, those of us in the Northern Hemisphere will welcome spring with the arrival of the vernal equinox.

This will be the earliest vernal equinox in 124 years. Traditionally we celebrate the first day of spring on March 21, but astronomers and calendar manufacturers alike now say the spring season starts on March 20th in all North American time zones. And this year it’s even earlier.

Regardless of the equinox marking the official start of the spring season, to me it feels as if spring has already begun here in Los Angeles and I am kicking it off with a big sale!

How can the first day of spring change from year to year?

There are a few reasons why seasonal dates can vary from year to year.

1. A year does not contain an even number of days and neither do our seasons.

2. This one is super fascinating to me: The earth’s elliptical orbit is changing its orientation (skew), which causes the earth’s axis to constantly point in a different direction, called precession. The seasons are defined as beginning at strict 90-degree intervals, so these positional changes affect the time the earth reaches each 90-degree location in its orbit around the sun. In other words – the only thing constant is change, folks.

3. The pull of gravity from the other planets also affects the location of the earth in its orbit. The current seasonal lengths for the northern hemisphere are:

Summer — 93.641 days
Autumn — 89.834 days
Winter — 88.994 days
Spring — 92.771 days

The warm seasons, spring and summer, add up to 7.584 more days than the colder seasons, fall and winter – which is good news for warm weather lovers.

However, this is changing too. Spring shortens by approximately one minute per year and winter by about half a minute per year. Summer is gaining the minute lost from spring, and autumn is gaining the half minute lost from winter. Winter is the shortest astronomical season, and with its seasonal duration continuing to decrease, it is expected to attain its minimum value — 88.71 days — by about the year 3500!!!!
