photoage.calculate_days('/path/to/photo.jpg',
        birthday=datetime.datetime(2017, 6, 6),
        offset=datetime.timedelta(hours=3))

# same, except that it specifies the methods to find out the date time of the photo
# by the way, the default value of the argument `methods` is `('exif',)`
# the current supported methods are "exif" and "stat"
photoage.calculate_days('/path/to/photo.jpg',
        birthday=datetime.datetime(2017, 6, 6),
        methods=('exif', 'stat'))

# get the date time from a photo
# it will return a datetime.datetime object
photoage.get_date_time('/path/to/photo.jpg')
