Numpy, TypeError: Could not be cast from dtype('<M8[us]') to dtype('<M8[D]')

Question

I\'m trying to find out number of business days until a specific date and get the following error:

import numpy as np
import pandas_market_calendars as mcal         


        

Answer 1

You should pass dates to busday_count rather than datetimes:

In [11]: today = datetime.now()
    ...: expiration = datetime(2019,2,13,0,0)
    ...:
    ...: days_to_expiration = np.busday_count(today.date(),expiration.date(),holidays=holidays)
    ...: print(days_to_expiration)
11
