Reference for Rosh Hashanah 12:7

הניחא למאן דאית ליה כסדרן משכחת לה אלא למאן דלית ליה כסדרן היכי משכחת לה

[To revert to] the [above] text: '[The rule] both for a firstling and for all consecrated animals is that so as they have been kept back a year even without three festivals or three festivals even if less than a year, the precept of "not delaying" is trans gressed'. I grant that three festivals without a year are possible; but how i a year possible without three festivals?
