I don't think that there's an existing library that works for this. You have to make something yourself, like this:

monthdays = (31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31)

day = 32

total = 0
for i in monthdays:
    if day - total - i < 0:
        before = day - total
        after = total + i - day
        break
    total += i

print before, after

(just a quick start, there is possibly a more elegant way)
