First day of Sprint, first day of the calendar.
 

Hey, I want to bring my life into sync with nature better by mentally observing the beginning of a calendar at the beginning of Spring. I need some help finding a calendar that starts on the first day of spring as witnessed by when the Earth is actually just entering the Spring position in relation to the sun. (March 1st I heard actually isn't the first day, but if an astrologer can help determine what Gregorian day the first day of Sprint truly is, I'd be quite happy. I need a calendar that will both allow me to see the Gregorian day for that as well as the day of that calendar. (For those of you who don't know what the Gregorian calendar is, it's the most common calendar used in the western world. It starts on January 1st and ends on December 31st.)

Thanks for your help everyone in advance!

Namaste

Today is the 3rd of october
