Related for Rosh Hashanah 14:2
ותנא דידן כיון דקתני אם הביא יצא לא פסיקא ליה:
Why does our Tanna [not reckon New Year for shekalim]? - Since it is laid down that if the sacrifices are brought [from the old contributions] the duty is still performed, he was not certain [whether this should be counted a New Year].' Some say, Also for the renting of houses'.
Tosefta Rosh Hashanah (Lieberman)
How [one should understand]: "for house rent"? [Answer:] If he rents a house to another for a year, he counts twelve months from the day he started renting it to him. But if he says: For this year, even if he rented it from him only on the first of Adar, he owns it only up to the first of Nisan.
