for general knowledge:
Maslenica is a (free) Slavic Festival celebrating spring and pancakes.
Russians love both: spring because it is not winter and pancakes because they go with anything: tea, caviar, butter, honey, mayo and even chicken.
astronomical excursion:
The March equinox (or Northward equinox) is the equinox on the earth when the Sun appears to cross the celestial equator, heading northward. The March equinox is the vernal equinox in the Northern Hemisphere and the autumnal equinox in the Southern Hemisphere.
The equinox can be as early as March 19 or as late as March 22, the precise time being about 5 hours 49 minutes later in a common year, and about 18 hours 11 minutes earlier in a leap year, than in the previous year. It is the balance of common years and leap years that keeps the calendar date of the equinox from drifting more than a day from March 20 each year.
We celebrate the March equinox by traditions of Northern hemisphere (neglecting that everything is upside down here) and according to Vedic ancient culture, but Christians celebrate it earlier: check out this sites - http://ru.maslenitsa.com.au/p/home.html andhttps://www.facebook.com/pages/Maslenitsa-Slavic-Pancake-Festival/175756975827866
