Each month, Sailor Moon Crystal airs only 2 episodes, releasing them every 2 weeks on Saturday.
If a month has 5 Saturdays on it, the next episode after the 2nd episode it airs on that month will air in 3 weeks instead.
For next month of November, because there's 5 Saturdays, only Nov 1 (which will air this week on Saturday) and Nov 15 will have Sailor Moon Crystal. Nov 29 will not show the next new episode until Dec 6.
