[Calendar] century handler for short year (dd.mm.yy) input

[MarcelMpunkt]

Feature Request

Description

if the user inputs the year in short form like this: dd.mm.yy
it is automatically corrected to: dd.mm.yyyy

there should be an option to control which years are put in which centuries

At the moment if you input:
11.12.59 it is corrected to 11.12.2059
if you input:
11.12.60 it is corrected to 11.12.1960

Example

maybe it could be controlled via years

e.g. 100 years (2019-100=1919)
>= currentYear
19 -> 1919
20 -> 1920
88 -> 1988
< currentYear
18 -> 2018
4 -> 2004
12-> 2012
