Today is reverse D5
Tomorrow is both 5:5 ''and'' a "D5" if using reduction method on the 13th letter (M for "May", 1+3=4…D=4)
__124__th day of year. "Multiple" day news event referred to by Q could be a "24" reference, since x is the 24th letter and it represents "multiples"/multiplication.
241 days left in year…anagram of 124.
Initial reports of total people on board crashed plane were "142"…also an anagram of those digits.
Could be somethin'.
