PPM 3018.15 PARA 9A1. An OBR will not exceed 5 days.
PARA 9.A.2 ....may exceed 4 days once per month. Meaning 4 four day OBRs plus a 3 day carrying over into the next month is completely allowed..
also a 5 day OBR is allowed month 1 then carrying a 4 day block with a single day into the next month is perfectly allowed.
