Windows has separate date and time commands ('date /t' and 'time /t'),
but it's simpler to use 'echo %time% %date%' in the shell.
Also, the demo script isn't for Python 3.x. It uses "print" as a
statement and the "commands" module, which is deprecated in 2.x and
removed from 3.x.
Try this instead:
import sys
import os
import subprocess
from dateutil.relativedelta import *
from dateutil.easter import *
from dateutil.rrule import *
from dateutil.parser import *
from datetime import *
if sys.platform == 'win32':
cmd = 'echo %time% %date%'
shell = True
else:
cmd = 'date'
shell = False
datestr = subprocess.check_output(cmd, shell=shell).decode()
now = parse(datestr)
today = now.date()
year = rrule(YEARLY,bymonth=8,bymonthday=13,byweekday=FR)[0].year
rdelta = relativedelta(easter(year), today)
print("Today is:", today)
print("Year with next Aug 13th on a Friday is:", year)
print("How far is the Easter of that year:", rdelta)
print("And the Easter of that year is:", today+rdelta)
