Official the spring solstice is 20th March but actually here in the northern hemisphere it happens a little earlier for all of us for instance here on the south coast our nearest to equal day and night will be on Monday 18th Sunrise will be 06.13 and sunset 18.14. so we start spring two days early ☀😎😊

The official version: 
An equinox is commonly regarded as the instant of time when the plane of Earth's equator passes through the centre of the Sun. This occurs twice each year: around 20 March and 23 September. In other words, it is the moment at which the centre of the visible Sun is directly above the Equator.

  • The Equinox is as the official version states. However, this is NOT the same time as equal day and night. For one thing, atmospheric refraction makes the Sun seem higher than it is. Also, the Sun is not a point but a disc, and sunrise is when just the top of the disk is visible. These two effects make days slightly longer than they would otherwise be. In the Autumn, day and night are equal length a few days after the Equinox.

    No the equinox gives exactly equal day and night if you are on the equator on the 20th March or 23rd September the rest of the world north or south is different I was asking when people get there equal day night I understand the system why and how completely it was just a simple question.

    Here in Billericay, according to BBC Weather, on the 18 Mar the sun rises at 06:07 and sets at 18:07
    A nugget I read or saw somewhere indicated that Spring travels from South to North at approx 2 mph - and only 2 weeks to go until the clocks spring forward - hooray!!

    The clocks going forward always makes me feel spring has really arrived that extra time in the garden in the evening 🍷😎

    Not true. for Singapore, 1 degree north of the Equator, the day length is a few minutes more than 12 hours every day, for the reasons I have given.

    On Earth, daytime is roughly the period of the day during which any given point in the world ... Although the daytime length at the Equator remains 12 hours in all seasons, the duration at all other latitudes varies with the seasons. ... is usually a few days before the spring equinox and extends a few days past the fall equinox).

    For me, and the rest of the UK, the equinox is on the 20th, but approximately equal day and night (12:01 day, 11:59 night for me) is on the 18th. Near the spring/autumn equinoxes the rate of change of day length is at its greatest, so on the 19th the day is nearly four minutes longer than the 18th, so 12:05 day, 11:55 night. And a jolly good thing too :smile:

    18th here for equal day and night - 6.22 - 18.23.

    I count the equinox as being when the sun sets directly behind the barn on the hill opposite. It needs to not be raining for me to notice, which hasn't happened for a while

    Solstice happens in summer and winter and marks the longest and shortest days.

    Equinox happens in spring and autumn when day length is equal to night length and that's a movable feast depending on your latitude.  If you're on the equator, equinox is barely different from solstice.
