The old prediction had DST going until late October, except not during Ramadan, 
and those dates were predicted to be the last Sunday before Ramadan.  The 
proposed new prediction has DST going until late September, so Ramadan already 
safely falls after DST ends in those two years, and there's no longer any need 
for those two special cases.
