Are these stored as intervals?
=> SELECT extract(month from justify_days('14 weeks'::interval)); date_part
----------- 3
(1 row)
=> SELECT extract(month from justify_days('1 week'::interval)); date_part
----------- 0
(1 row)
If you just have a number (e.g. 14) then you can just do something like:
=> SELECT round(14 * 7 / 30); round
------- 3
(1 row)
