In the Gemara in Rosh Hashanah 6b, it is found: [In the case of] all consecrated animals — once a year has passed without three Festivals, or three Festivals have passed without a year [elapsing, the owner] transgresses, you shall not delay. Then the Gemara asks: Granted, three Festivals without a year can be found. But a year without [three] Festivals, how can you find it?
