Add minutes to a date and subtract minutes from a date without using any Python library

	import sys
	def sum_minutes_to_date(str_date, minutes):
	date, hour = str_date.split(' ')
	day, month, year = date.split('/')
	day = int(day)
	month_start_with_0 = False

	if month.startswith('0'): month_start_with_0 = True

	month = int(month)
