You won't get any definite answer to your question because there are so many variables. It will depend on how many bees you have, how motivated they are to make new comb for brood or honey, how much nectar flow is going on, how much pollen is available for brood rearing etc. In the spring it could happen in two weeks if everything is going full blast. Or it might not happen this year if they don't need the space, are in a long dearth etc. Observe the hive carefully and maybe you can tell how motivated they are and if they have the necessary resources.
