The official change in the seasons – from Winter to Spring – occurs tomorrow, Thursday, Mar. 20 at 2.27 p.m. in Newfoundland and Labrador.

Spring showers bring May flowers and the onset of summer!

And as Newfoundland inshore fishermen kept a watchful eye out for – winds will be light and out of the easterly when the sun crosses the line, tending to a mild but wet spring.

It officially marks the change in the season, a time when there is one of two equinoxes every year – in March and September. The dates mark when the sun shines directly on the equator and the length of day and night is nearly equal.

According to ‘timeanddate.com’, seasons are opposite on either side of the equator, so the equinox in March is also known as the 'spring equinox' in the northern hemisphere.

However, in the southern hemisphere, it’s known as the 'autumnal (fall) equinox'.

On the equinox, night and day is nearly exactly the same length – 12 hours – all over the world. This is the reason it’s called an ‘equinox’, derived from Latin, meaning ‘equal night’.

However, even if this is widely accepted, it isn’t entirely true. In reality equinoxes don't have exactly 12 hours of daylight.

The March equinox occurs the moment the sun crosses the celestial equator – the imaginary line in the sky above the Earth’s equator – from south to north. This happens either on Mar. 19, 20 or 21 every year.

On any other day of the year, the Earth’s axis tilts a little away from or towards the Sun. But on the two equinoxes, the Earth’s axis tilts neither away from nor towards the Sun.
