Lunar New Year, Chinese Holidays Won't Be Added to School Calendar This Year

I was surprised that 80% of Chinatown's P.S. 130 have been absent on the Chinese New Year. 14% of NYC students are Asian.

Of course the challenge is the state requires 180 days of instruction, and the current school year is 182-183 days per year. Where do you get the extra days for the holiday?
