As the prophecy of "seven times" [insert scripture here] was inspired by jehovah [insert scripture here] then he knew that "in the last days" [insert scripture here] true light will be abundant. [insert scripture here]
Evidently jehovah knew [insert scripture here] that the Jewish and Gregorian calenders kept different numbers of days. Hence as the great time keeper [insert scripture here] jehovah could foresee [insert scripture here] that his prophecy would need to take into account the overlapping years [insert scripture here] so that true correct date would fit in with accurate teachings of the Watchtower. [insert scripture here]
Are we not happy brothers that jehovah pointed to 1914 as the start of his kingdom [insert scripture here] and the appointment of the "faithful and discreet slave" [insert scripture here] in 1919.
Clearly jehovah has our best intests at heart [insert scripture here] by revealing to "the slave" [insert scripture here] the times and seasons. [insert scripture here]
