Hi Team - may I know why Jazz trio is possible to be on May 1? Isn't that O must be ahead of J that J can never be on the first day? Thanks!

The first rule means that whenever you have an O, you must have a J right after it. That does not mean that whenever you have a J there must be an O before it - that would be a Mistaken Reversal of that rule. Putting a J in the first position wouldn't violate that rule about what you have to do when you place an O.

The rule could be written like this:

O OJ

The O is Sufficient, not the J. A J doesn't require you to do anything!
