I personally always feel like the real new year begins with the Lunar New Year in Late January, early February. Somehow it always feels more authentic than the chronology of the Gregorian calendar.
But there are many new years to be had at any given moment! The Tibetan New Year, or Losar, begins today. Tsagaan Sar, the Mongolian New Year, starts today as well. Celebrate with some quiet time at the Freer Sackler during the day or some meditation at the Shambala Center at night (7pm), or both!
