pical

pical is a python icalendar library.

Supported features:

• parsing, building an ics file (icalendar version 2.0/rfc5545,rfc2445)
• querying for component with time-range (caldav/rfc4791)
• values will be accessible as python native types

Unsupported features:

• leap second support
• floating values with precision higher than double

Simple usage:

from datetime import datetime
import pical
cals = pical.parse(open("tests/google_calendar_ex1.ics"))
cal = cals[0]
# subcomponents are stored in children
for c in cal.children:
       if c.name == "VEVENT":
               print c["DTSTART"]

Time-range query example:

from datetime import datetime
import pical
cals = pical.parse(open("tests/google_calendar_ex1.ics"))
expcal = cals[0].time_range(expand=[datetime(2010,1,1,tzinfo=pical.utc), datetime.now(pical.utc)])
for line in expcal.clone(in_utc=True).serialize():
       print line
