Summary

DateTimeRange <https://github.com/thombashi/DateTimeRange>__ is a Python library to handle a time range. e.g. check whether a time is within the time range, get the intersection of time ranges, truncating a time range, iterate through a time range, and so forth.

Examples

Create a DateTimeRange instance from start and end datetime

:Sample Code: .. code:: python

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

:Output: ::

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

Create a DateTimeRange instance from a range text

:Sample Code: .. code:: python

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

:Output: ::

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

Get an iterator

:Sample Code 1: .. code:: python

    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)

:Output 1: ::

    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

:Sample Code 2: .. code:: python

    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)

:Output 2: ::

    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

:Sample Code: .. code:: python

    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)

:Output: ::

    True
    False
    True

Test whether a value intersect the time range

:Sample Code: .. code:: python

    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)

:Output: ::

    True

Make an intersected time range

:Sample Code: .. code:: python

    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)

:Output: ::

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

Make an encompassed time range

:Sample Code: .. code:: python

    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)

:Output: ::

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

Truncate time range

:Sample Code: .. code:: python

    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)

:Output: ::

    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)
