For CFA(US), generally as per Institute , you need to devote 250-300 hours of study. Also, in my view regular study is important.
Its good that you will have leave for one month, but still i suggest to make a plan and try to cover some topics early also. Since in the last months , you need to solve some sample papers, which i think is important to have a feeling of the exam pattern.
