Since shallots are barely cold tolerant you can plant them just a tiny bit earlier in the year than more sensitive plants.

The last month that you can plant shallots and expect a good harvest is probably August. Any later than that and your shallots may not have a chance to really do well. If you are starting your shallots indoors then you might be able to get away with starting them a couple of weeks earlier.

Last Frost Date
