Question

I have a string \"2012.11.07\" in python. I need to convert it to date object and then get an integer value of day of year and also Julian day

Answer 1

def JulianDate_to_date(y, jd):
    month = 1
    while jd - calendar.monthrange(y,month)[1] > 0 and month <= 12:
        jd = jd - calendar.monthrange(y,month)[1]
        month += 1
    date = datetime.date(y,month,jd).strftime("%m/%d/%Y")
    return date
