What week of the month is it?

pendulum v2.1.0 on macOS

>>> import pendulum
>>> d = pendulum.Date(2019, 12, 31)
>>> d.week_of_month
-46

Isn't new years day 2019 the week 5 of the month?

How to interpret week of the month result negative 46?

You can use calendar:

import calendar
import numpy as np
calendar.setfirstweekday(6)

def get_week_of_month(year, month, day):
    x = np.array(calendar.monthcalendar(year, month))
    week_of_month = np.where(x==day)[0][0] + 1
    return(week_of_month)

get_week_of_month(2019,12,31)

Output:

5

This is what they use:

def week_of_month(d):
    first_day_of_month = d.replace(day=1)
    print(d.week_of_year,first_day_of_month.week_of_year)

    return d.week_of_year - first_day_of_month.week_of_year + 1

week_of_month(d)

Bug is here

first_day_of_month.week_of_year gives --> 48

Earlier they were using this:

import math
def week_of_month(d):
        return int(math.ceil(d.day / 7))

which gives correct output
