There is an ancient practice at this time of the year to reflect on exactly 1/2 year from now, as we head into days of Pesach, 1/2 year from Sukkos.
In most leap years, opening verses of Acharei Mos [Keri’as haTorah of Y’K morning} are actually leined on Nisson 10th, be it a Monday morning or Thursday morning [then only 50% of the time] or Shabbos Mincho; This timing clearly is no accident.
