The Year Only module provides this feature by defining a new field type.
.
It comes with a range configuration.
It produces the following result in the entity (node, ...) edit form. Configured with unlimited number of values in this example.
I would personally recommend following https://drupal.stackexchange.com/a/242011/5438. It's a little more work with some coding but it doesn't mean you need to add another module that needs to be supported in relation to many drupal areas. You can use a List (integer) field and add things there.
You can can also use a field_integer textfield and use a form alterer.

The link suggests creating a custom module so I don't see the benefit here? Aug 12, 2020 at 17:44

1@DanielHarper it's a helper module that uses a core API hook, this means you will hardly have to update it and it uses core's field types instead of one provided by a module. The level of maintainability is considerable less IMO. I did say it was a personal recommendation, this is the reasoning behind it. Aug 13, 2020 at 21:39
You can use Date module.
This package contains both a flexible date/time field type Date field and a Date API that other modules can use.
When you add field you can choose what you want to show (day, month, year) and + and - from current year.

1This was only the case for the D7 module. Date in core does not have these options.– tancMay 25, 2017 at 13:52
