Usage

DateRange

DateRange helps you to calculate number of days, weeks, quarters or years in date ranges.

Example Code:

from datetime import date
from DateRanger import DateRanger
from DateRanger.objects import DateRange

r = DateRange(date(2014, 11, 1), date(2014, 12, 1))
print r.months()
print r.days()

Other useful methods

r.days()
r.weeks()
r.months()
r.quarters()
r.years()

r.each_day()
r.each_week()
r.each_month()
r.each_quarter()
r.each_years()

r.get_range()

DateRanger

To use this module, first we need to set the base_date. Base_date can be any date in the past, present and future. Default base_date is the present date which is TODAY (date.today()). Based on the date given, this module helps us to find in what week, quarter or year this date falls in.

For example:

If base_date is datetime.date(2015, 1, 19), then the relative date ranges would be:

base_week => datetime.date(2015, 1, 18) ~ datetime.date(2015, 1, 25) The week that contains base_date.

base_month => datetime.date(2015, 1, 1) ~ datetime.date(2015, 2, 1) The month that contains base_date.

base_quarter => datetime.date(2015, 1, 1) ~ datetime.date(2015, 4, 1) The quarter that contains base_date.

base_year => datetime.date(2015, 1, 1) ~ datetime.date(2016, 1, 1) The year that contains base_date.

prev_week => datetime.date(2015, 1, 11) ~ datetime.date(2015, 1, 18) Date range of previous week.

prev_month => datetime.date(2014, 12, 1) ~ datetime.date(2015, 1, 1) Date range of previous month.

next_week => datetime.date(2015, 1, 25) ~ datetime.date(2015, 2,1) Date range of next week.

next_month => datetime.date(2015, 2, 1) ~ datetime.date(2015, 3, 1) Date range of next month.

Example Code:

from datetime import date
from DateRanger import DateRanger
from DateRanger.objects import DateRange

dr = DateRanger()
test_range = dr.prev_month(2)
print test_range.get_range()

Other useful methods

dr.set_base_date(date)
dr.get_base_day()
dr.base_week()
dr.base_month()
dr.base_quarter()
dr.base_year()

dr.prev_week(2)
dr.next_week(2)

dr.prev_month(2)
dr.next_month(2)

dr.prev_quarter(2)
dr.next_quarter(2)

dr.prev_year(2)
dr.next_year(2)

dr.from_date(date)
dr.to_date(date)
