Python Date
Calculate Date Duration in Python
Recently, I created a function to calculate the number of days from today. This simple function accepts a date object and returns the number of Years, Months, and Days between now and that event.
I used the Relativedelta object from the Date library. It's an easy way to do the converting with a few lines of code. Since Relativedelta is part of Python3, it will scale very nicely.
The Relativedelta type has a lot of the same attribute that is found in PHPs Date library.
In the example below I was able to convert a 10 line PHP function to 3 lines of code. I am sure there's even more refactoring that can be done.
#!/usr/bin/env /usr/bin/python3
from datetime import date
from datetime import datetime
from dateutil import relativedelta
NOW = datetime.now()
def datecal(someday):
caldate = relativedelta.relativedelta(NOW,someday );
return f"{caldate.years} years, {caldate.months} months. {caldate.days} days";
day1 = datecal(date(1775,7,4))
print(day1)
# 246 years, 5 months. 3 days
