Datepicker mm/dd/y format doesn't support years before 1929

[jvic]

Datepicker with format, where is not complete year part (e.g. "mm/dd/y") doesn't support years before 1929.

Steps to reproduce: 1) Select some date before 1929

See demo: ​http://jsfiddle.net/Lhk94t8z/7/ Browser: Chrome

Year 1928 is ok. Problem is from year 1926.

Correct 1926, because today we are in 2015 and the shortYearCutoff defaults to "+10" (see the ​documentation). I'm not sure how you expected this to work since it's completely ambiguous.

[jvic]

You are wrong.

Check this updated jsfiddle: ​http://jsfiddle.net/Lhk94t8z/8/ If I call setDate() with Date object (year 1912) and after that I call getDate() datepicker must return same value.

[Scott González]

That's impossible since the canonical source is lossy, as specified by you via the date format.

Hi,

1) It's possible. Datepicker has internally stored date object. There is no loss, when user don't edit input manually. I prepared nasty fix: ​http://jsfiddle.net/Lhk94t8z/9/

2) If it's not bug, please explain why following UC in this jsfiddle (​http://jsfiddle.net/Lhk94t8z/8/) returns 1912.

• setDate (1912)
• getDate (2012)
• setDate (1912)
• getDate (1912)

#2 sounds like a bug.

[jvic]

Should I open new ticket with #2?

[Scott González]

If you want to. Considering this is tied to lossy date formats, I'm not sure it will be fixed before the rewrite is done, unless someone sends a PR.
