Its Spring Time! Or Autum?

    Hey! I hope you are all doing well! If you didnt noticed that yet, today the seasons are changing. For some, like for us, spring starts (South Hemisphere). While for others, Autumn (or Fall) is starting (North Hemisphere). Do you know how is this called? I didnt. Not at least before I wrote this and before I searched it in Google. In english its called Equinox and it is a point in time commonly used to determine the length of the tropical year.

    Due to the differences between the calendar year and the tropical year, the September equinox can happen anytime between September 21 and 24. So even if we celebrate, for example, spring on September 21st, it can happen that spring doesnt really start yet. For us, yesterday was the Spring Day, even if today is the spring equinox.

    At the equinox, the Sun seen from the equator rises east and sets west. Before the equinox, the sun rises and sets further north, and then rises and sets further south. The equinox can be taken to mark the end of the astronomical summer and the beginning of the astronomical autumn (autumnal equinox) in the Northern Hemisphere, while it marks the end of the astronomical winter and the beginning of the astronomical spring (vernal equinox) in the southern hemisphere.

    The autumn and spring equinoxes mark the point on the calendar where the length of the night and the length of the day are almost exactly the same. And seriously I think that sounds amazing.

    I also consider amazing the fact that, while for us its starting to be hot and the days are turning brighter, for the other half of the world is happening quite the oppsite. While for us flowers start to blossom, for the other half of the world leaves start to fall. Isnt nature incredibly awesome and interesting? We think it really is.

 

                                               

    We hope you an amazing Spring/Autumn, depending on where on the world you are now!
