Here is a regex if you want to find a year in a film name for example. Years b/n 1900 - 2029 and some symbols are allowed wrapping the year .-_+[(

(?<=(?:\s|\.|_|\-|\+|\(|\[))(?:19[2-9]|20[0-2])\d(?=\s|$|\.|_|\-|\+|\)|\])

Note you can not start with year, because there is at least interval in front. In the example first few lines are matching, because we have multiple lines in a single line they wont match.

1917.2019.1080p... even if 1917 was in range it will mark only 2019
