What Is This?

Timespans allow you to check if a timestamp falls within a specified list of boundaries. For example, you might want to program your phone system to only accept calls Mon-Fri from 9 a.m. to 5 p.m. except on holidays like Christmas.

Timespans are specified in the form of times|daysofweek|days|months. If your timespan starts with !, it'll only match if the timestamps falls outside the given range.

Basic example:

import timespan
from datetime import datetime

business_hours = [
    '9:00-17:00|mon-fri|*|*',  # is between 9 a.m. to 5 p.m. on Mon to Fri
    '!*|*|1|jan',              # not new years
    '!*|*|25|dec',             # not christmas
    '!*|thu|22-28|nov',        # not thanksgiving
]

if timespan.match(business_hours, datetime.now()):
    print "we're open for business!"
else:
    print "sorry, we're closed :("
