[Python] calculate age in python using numpy/any other package which considers US Holidays +...

I want to calculate the age (Day & Hr e.g. 1 Day 8Hr ) since the record was created. But it should not consider the weekend + US holidays.

Currently, I am using Numpy, but if some other package can do the same, then it's fine for me

Issues using numpy:

1. 
   While using numpy function busday_count, this function does consider time, i.e., if a record is created on 1st June at 10 AM and and current time is 2nd June at 8 AM then this function still gives me day difference 1, but its not correct age 1 day will get completed at 2nd June 10 AM so the date count which I want should be 0
   
   
2. 
   As per my knowledge, there is nothing in numpy for calculating time difference which takes weekends and us holidays into consideration like the busday_count function of numpy
   

import holidays


def age(self):
dates = []
current_year = timezone.now().year
for i in holidays.US(
years=[current_year - 1, current_year, current_year + 1]
).keys():
dates.append(i)
bdd = np.busdaycalendar(holidays=dates)

# Get day difference
day = np.busday_count(
self.record_created_at.date(), timezone.now().date(), busdaycal=bdd
)

age = timezone.now() - self.record_created_at

# Get time difference
hour = math.ceil(age.seconds / 60 / 60) - 1
data = {"day": day, "hour": hour, "label": f"{day}d {hour}h"}
return data
