I I noticed a lot of people don't know how the opening/ending schedule works. It's actually really simple so here is how it goes:
First week of January: New ED
First week of April: New OP and ED
First week of July: New ED
First week of October: New OP and ED
Repeat (back to January)
This rotation has remained exactly the same for over 5 years in a row, so expect the next OP/ED to start on October 3rd.
