[If] one says [it happened] on the second of the month and one says [it happened] on the third of the month, their testimony is upheld, because this one is aware of the intercalation of the month and this one is not aware of the intercalation of the month. [If] one says [it happened] on the third and one says [it happened] on the fifth, their testimony is null. [If] one says [it happened] in the second hour [of the day] and one says [it happened] in the third hour [of the day], their testimony is up-held. [If] one says [it happened] in the third [hour] and one says in the fifth, their testimony is null. R’ Yehudah says: It is up-held. [But if] one says [it happened] in the fifth [hour] and one says in the seventh, their testimony is null, because in the fifth [hour] the sun is to the east while in the seventh [hour] it is to the west.
