DateTimeRange

Summary

DateTimeRange is a python library to handle routine work associated with a time range, such as test whether a time is within the time range, get time range intersection, truncating the time range, etc.

Examples

Create and convert to string

from datetimerange import DateTimeRange
time_range = DateTimeRange("2015-03-22T10:00:00+0900", "2015-03-22T10:10:00+0900")
str(time_range)

'2015-03-22T10:00:00+0900 - 2015-03-22T10:10:00+0900'

Get iterator

import datetime
from datetimerange import DateTimeRange

time_range = DateTimeRange("2015-01-01T00:00:00+0900", "2015-01-04T00:00:00+0900")
for value in time_range.range(datetime.timedelta(days=1)):
    print value

2015-01-01 00:00:00+09:00
2015-01-02 00:00:00+09:00
2015-01-03 00:00:00+09:00
2015-01-04 00:00:00+09:00

from datetimerange import DateTimeRange
from dateutil.relativedelta import relativedelta

time_range = DateTimeRange("2015-01-01T00:00:00+0900", "2016-01-01T00:00:00+0900")
for value in time_range.range(relativedelta(months=+4)):
    print value

2015-01-01 00:00:00+09:00
2015-05-01 00:00:00+09:00
2015-09-01 00:00:00+09:00
2016-01-01 00:00:00+09:00

Test whether a value within the time range

from datetimerange import DateTimeRange
time_range = DateTimeRange("2015-03-22T10:00:00+0900", "2015-03-22T10:10:00+0900")
print "2015-03-22T10:05:00+0900" in time_range
print "2015-03-22T10:15:00+0900" in time_range

time_range_smaller = DateTimeRange("2015-03-22T10:03:00+0900", "2015-03-22T10:07:00+0900")
print time_range_smaller in time_range

True
False
True

Test whether a value intersect the time range

from datetimerange import DateTimeRange
time_range = DateTimeRange("2015-03-22T10:00:00+0900", "2015-03-22T10:10:00+0900")
x = DateTimeRange("2015-03-22T10:05:00+0900", "2015-03-22T10:15:00+0900")
time_range.is_intersection(x)

True

Make an intersected time range

from datetimerange import DateTimeRange
time_range = DateTimeRange("2015-03-22T10:00:00+0900", "2015-03-22T10:10:00+0900")
x = DateTimeRange("2015-03-22T10:05:00+0900", "2015-03-22T10:15:00+0900")
time_range.intersection(x)
time_range

2015-03-22T10:05:00+0900 - 2015-03-22T10:10:00+0900

Make an encompassed time range

from datetimerange import DateTimeRange
time_range = DateTimeRange("2015-03-22T10:00:00+0900", "2015-03-22T10:10:00+0900")
x = DateTimeRange("2015-03-22T10:05:00+0900", "2015-03-22T10:15:00+0900")
time_range.encompass(x)
time_range

2015-03-22T10:00:00+0900 - 2015-03-22T10:15:00+0900

Truncate time range

from datetimerange import DateTimeRange
time_range = DateTimeRange("2015-03-22T10:00:00+0900", "2015-03-22T10:10:00+0900")
time_range.is_output_elapse = True
print "before truncate: ", time_range
time_range.truncate(10)
print "after truncate:  ", time_range

before truncate:  2015-03-22T10:00:00+0900 - 2015-03-22T10:10:00+0900 (0:10:00)
after truncate:   2015-03-22T10:00:30+0900 - 2015-03-22T10:09:30+0900 (0:09:00)
