Python Question: Year and Day of Year to date?

Is there a method in Python to figure out which month a certain day of the year is in, e.g. today is day 299 (October 26th). I would like to figure out, that day 299 is in month 10 (to compile the string to set the Linux system time).
How can I do this?

Answer 1

print (datetime.datetime(2012,1,1) + datetime.timedelta(days=299)).month

Here’s a little more usable version that returns both the month and day:

def get_month_day(year, day, one_based=False):
    if one_based:  # if Jan 1st is 1 instead of 0
        day -= 1
    dt = datetime.datetime(year, 1, 1) + datetime.timedelta(days=day)
    return dt.month, dt.day

>>> get_month_day(2012, 299)
(10, 26)
