0 Happy First Day of Spring! March 20

It may not feel like the first day of spring in some parts of the country, but today in Rockport-Fulton we are enjoying almost perfect weather. Perfect temperature, slightly breezy, with that warm sun you want to lay in all day. The first day of spring is also known as an equinox. Here's some interesting info from Wikipedia about what that means....

An equinox occurs twice a year (around 20 March and 22 September), when the plane of Earth's equator passes the center of the Sun. At this time the tilt of the Earth's axis is inclined neither away from nor towards the Sun. The term equinox can also be used in a broader sense, meaning the date when such a passage happens.

Another meaning of equinox is the day when daytime and night are of approximately equal duration. The word equinox is based on this fact, derived from the Latin aequus (equal) and nox (night). The equinox is not exactly the same as the day when period of daytime and night are of equal length for two reasons. Firstly, sunrise, which begins daytime, occurs when the top of the Sun's disk rises above the eastern horizon. At that moment, the disk's center is still below the horizon. Secondly, Earth's atmosphere refracts sunlight. As a result, an observer sees daylight before the first glimpse of the sun's disk above the horizon. To avoid this ambiguity, the word equilux is sometimes used to mean a day on which the periods of daylight and nighte are equal.[4][note 1] Times of sunset and sunrise vary with an observer's location (longitude and latitude), so the dates when day and night are of exactly equal length likewise depend on location.  source link
