PyTime is a easy-use Python module which aims to operate date/time/datetime by string.
PyTime allows you using nonregular datetime string to generate and calculate datetime at most situation.
It Also provides you some simple useful methods for getting datetime you want.
pip install pytime
Calculate datetime all by string, accept unit for short or overall length, support out of order or in capital unit:
>>>from pytime import pytime
>>>
>>>pytime.before('2015.5.17', '2years 3mon 3d 2hr' ) # 2years 3monhts 3days 2hours before 2015.5.17
datetime.datetime(2013, 2, 13, 22, 0)
>>>
>>>pytime.after(pytime.tomorrow(), '23month3dy29minu') # 23months 3days 29minutes after tomorrow
datetime.datetime(2017, 4, 19, 0, 29)
Parse nonregular datetime string to datetime stamp:
>>>pytime.parse('2015517')
datetime.date(2015, 5, 17)
>>>
>>>pytime.parse('5/17/15')
datetime.date(2015, 5, 17)
>>>
>>>pytime.parse('92-11-2')
datetime.date(1992, 11, 2)
Calculate week and month in a easy way. Normally we want to use these binate date in script, from Monday to next Monday which means 00:00:00-23:59:59, and Month from 1st to next 1st in the same way, but if you want clean date interval, you could set pytime.next_week(clean=True) to get the clean date for next week etc.
>>>pytime.this_week()
(datetime.date(2015, 5, 11), datetime.date(2015, 5, 18))
>>>pytime.next_week('2015-6-14') # 2015-6-14's next week for script
(datetime.date(2015, 6, 15), datetime.date(2015, 6, 23))
>>>pytime.last_week(pytime.mother(2013), True) # 2013 Mother's Day's last week
(datetime.date(2013, 5, 13), datetime.date(2013, 5, 20))
>>>pytime.next_month('2015-10-1')
(datetime.date(2015, 11, 1), datetime.date(2015, 12, 1))
Pytime support calculate timedelta by string even between date and datetime, merely set the date to that day's midnight:
>>>pytime.count('2015-5-17 23:23:23', pytime.tomorrow())
datetime.timedelta(1, 84203)
Get common festivals for designated year:
>>>pytime.father() # Father's Day
datetime.date(2015, 6, 21)
>>>
>>>pytime.mother(2016) # 2016 Mother's Day
datetime.date(2016, 5, 8)
>>>
>>>pytime.easter(1999) # 1999 Easter
datetime.date(1999, 4, 4)
Get days between two date.
>>>pytime.daysrange('2015-5-17', '2015-5-23')
[datetime.date(2015, 5, 23),
datetime.date(2015, 5, 22),
datetime.date(2015, 5, 21),
datetime.date(2015, 5, 20),
datetime.date(2015, 5, 19),
datetime.date(2015, 5, 18),
datetime.date(2015, 5, 17)]
...
and other useful methods.
