In ancient times, the Slavs celebrated the onset of spring with a big holiday. Celebrations took place widely, because the onset of spring was a symbol of the beginning of a new time. From that day on, it was possible to start a new cycle of field work, to engage in other agricultural work.
Before Christianity, the spring equinox was considered the beginning of the new year. After the baptism of Russia and the adoption of the Julian calendar, the chronology began to be conducted from March, or from the day of Holy Pascha.
At the First Ecumenical Council in Nicaea in 325, it was decided to postpone the beginning of the New Year from March 1 to September 1.
In December 1699, by the personal Decree of Peter I, it was established that the celebration of the New Year in Russia was postponed from September 1 to January 1.
