I can get the EXIF data from an image using PIL, but how can I get the date and time that the photo was taken?

Found the answer eventually, the tag I needed was 36867:
from PIL import Image
def get_date_taken(path):
return Image.open(path)._getexif()[36867]

I like to use exif-py because it's pure-python, does not require compilation/installation, and works with both python 2.x and 3.x making it ideal for bundling with small portable python applications.
Link: https://github.com/ianare/exif-py
Example to get the date and time a photo was taken:
import exifread
with open('image.jpg', 'rb') as fh:
tags = exifread.process_file(fh, stop_tag="EXIF DateTimeOriginal")
dateTaken = tags["EXIF DateTimeOriginal"]
return dateTaken

This has changed slightly in more recent versions of Pillow (6.0+ I believe).
They added a public method getexif() that you should use. The previous version was private and experimental (_getexif()).
from PIL import Image
im = Image.open('path/to/image.jpg')
exif = im.getexif()
creation_time = exif.get(36867)

ExifTags.TAGS is a mapping from tag to tag name. You can use it to create a map of tag names to values.
On this particular picture, there are a few different "date" properties (DateTime, DateTimeOriginal, DateTimeDigitized) that could be used.
import json
from PIL import Image, ExifTags
from datetime import datetime
def main(filename):
image_exif = Image.open(filename)._getexif()
if image_exif:
# Make a map with tag names
exif = { ExifTags.TAGS[k]: v for k, v in image_exif.items() if k in ExifTags.TAGS and type(v) is not bytes }
print(json.dumps(exif, indent=4))
# Grab the date
date_obj = datetime.strptime(exif['DateTimeOriginal'], '%Y:%m:%d %H:%M:%S')
print(date_obj)
else:
print('Unable to get date from exif for %s' % filename)
Output:
{
"DateTimeOriginal": "2008:11:15 19:36:24",
"DateTimeDigitized": "2008:11:15 19:36:24",
"ColorSpace": 1,
"ExifImageWidth": 3088,
"SceneCaptureType": 0,
"ExifImageHeight": 2320,
"SubjectDistanceRange": 2,
"ImageDescription": " ",
"Make": "Hewlett-Packard ",
"Model": "HP Photosmart R740 ",
"Orientation": 1,
"DateTime": "2008:11:15 19:36:24",
...
}

I create a function (get_exif) that can get attributes more easily.
USAGE
your_date_time: str = get_exif(Path('test.jpg'), 'DateTimeOriginal')
# your_date_time = get_exif(Path('test.jpg'), 0x9003) # same as above
get_exif
from pathlib import Path
from typing import Union, List, Tuple
import PIL.Image
import PIL.ExifTags
def get_exif(file_path: Path,
search_list: Union[int, str, List, Tuple] = None,
ignore_error=True
) -> Union[int, PIL.Image.Exif, List]:
"""
:param file_path: image path
:param search_list: if you want to get some property, then you can pass the id or name, it will return by order.
:param ignore_error:
:return:
int: -1 FileNotFoundError, or exif is None
PIL.Image.Exif: when the `search_list` is None, return the whole Exif
"""
tag_by_id: dict = PIL.ExifTags.TAGS
try:
im: PIL.Image.Image = PIL.Image.open(str(file_path))
except FileNotFoundError:
if ignore_error:
return -1
else:
raise FileNotFoundError(file_path)
exif: PIL.Image.Exif = im.getexif()
if not exif:
if ignore_error:
return -1
else:
raise ValueError("exif is None")
if search_list is None:
return exif
tag_by_name = {tag_by_id[dec_value]: exif[dec_value] for dec_value in exif if dec_value in tag_by_id}
result_list = []
if not isinstance(search_list, (list, tuple)):
search_list = [search_list]
for key in search_list:
if isinstance(key, int):
result_list.append(exif.get(key, None))
continue
try:
dec_value = int(key, 16)
result_list.append(exif.get(dec_value, None))
continue
except ValueError:
...
result_list.append(tag_by_name.get(key, None))
return result_list if len(result_list) > 1 else result_list[0]
MORE TEST
import unittest
class ExifTests(unittest.TestCase):
def test(self):
exif: PIL.Image.Exif = get_exif(Path('test.jpg')) # same as the ``PIL.Image.open().getexif()``

self.assertTrue(date_t_ori1 == date_t_ori2 == date_t_ori3)
# You can get multiple values at once. If the key does not exist, it returns None.
date_t_ori4, img_length, _, __ = get_exif(Path('test.jpg'),
(36867, 'ImageLength', 'NoteExitName', -12345))
# Occurring error return -1 (by default ignore_error=True)
