Mahāyāna New Year
Date: January 28
Mahāyāna (“the Great Vehicle”) is one of two main existing branches of Buddhism and a term for classification of Buddhist philosophies and practice.
The Mahāyāna New Year is celebrated at different times for each country and tradition – some celebrate on December 31 or January 1 along with many other new year celebrations, while other celebrate it at the first full moon, usually around mid-January.
For Buddhists, the new year is a time for meditation and self-reflection; improvement and learning from past mistakes. The most important activity of the new year is praying to their deities, particularly Buddha, and visiting temples to light candles which is considered good luck for the coming year.

Tu BiShvat, also known as “New Year of the Trees,” is Jewish Arbor Day. The holiday is observed on the 15th of the Hebrew month of Shvat.
It is thought Tu BiShvat was originally an agricultural festival, marking the emergence of spring. In Israel, the holiday has become a tree-planting festival, and Israelis and Jews around the world plant trees in honor or in memory of loved ones and friends.
