datefns 0.0.1a8

Getting Started

There are no dependancies to install. You just need to:

pip install datefns

or:

git clone git@github.com:ktr/datefns.git
cd datefns
python setup.py install

Once installed, you can iterate through the entire file without using much memory by doing the following:

import datefns, datetime
d1 = datetime.date(2018, 7, 10)
d2 = datetime.date(2018, 12, 31)
we = datefns.week_ending(d1, week_ends_on='Sun')
ds = datefns.date_table(d1, d2)
me = datefns.eomonth(d1, 5) # datetime.date(2018, 12, 31)

ts = datefns.time_table()

datefns.date_table_to_csv(ds, '/path/to/date-file.csv', overwrite=True)
datefns.time_table_to_csv(ts, '/path/to/time-file.csv', overwrite=True)

import sqlite3
conn = sqlite3.connect(':memory:')
datefns.load_date_table(conn, datefns.date_table(start_date=d1, end_date=d2))
datefns.load_time_table(conn, ts)

ds = datefns.date_range(d1, d2, datefns.by_month)
