Topic: Help - Lunar chart Spring Equinox - tommorow?

I looked up the lunar chart and it says 18, 19 of this month is best days for root work and it is the spring equinox, but I looked up and new moon is on 20th March and that is when it is spring equinox . 

From what i've read, we should only cut hair during the waxing phase of the moon and 18 and 19th would be the Waning phase. 

Also, I cross checked with other lunar calendars elsewhere on the internet and they all say not to cut hair on 18 and 19. 

Please help because 18th is tomorrow.
