OneYearAgo provides an Easy way to get the same day scenario (week, weekday, working day and holiday) for a previous year.
It's important to define that we understand "the same day" as the day in a previous year that accomplish:
- Same week of year
- Same weekday
- Ensuring that if the present day is a working day, the past day must be too; and viceversa
- (WIP) Ensuring that if the present day is a holiday the past day must be the more close date (if there are no more than 30days of difference between the gap) or XXX [issue #2]
Just import it # WIP pip installer [issue #1]
from one_year_ago.one_year_ago import OneYearAgo
and
logging.basicConfig(level=logging.DEBUG)
day=datetime(2016,5,1)
day=datetime.today()
a_year_ago = OneYearAgo(day)
## Get one year ago from the current day
a_year_ago.get_one_year_ago()
## To set a different past years to get
a_year_ago.get_year_ago(yearsago=2)
