Thailand and South Asia celebrate April 13th to 15th
Today’s New Year, coincident in 2009 with the Gregorian Easter Monday, was determined to coincide with the transit of the Sun into the Constellation (not to be confused with the astrological sign) of Aries. In 1930, the International Astronomical Union set the date at which the transit occurs at April 19th, however, due to the Precession of the Equinoxes, this date has likely drifted to April 20th by now (typically it falls a day later every 71 or 72 Years).
theAbysmal Calendar reforms the transit date to April 20th, which this Year bears the glyph 13~XX, the last nymber~glyph in the cycle of 260. This means that April 21st 2009 bears the first of the cycle, 1~I. This bodes well for new beginnings.
