getNumber = function( match ) {
      var isDoubled = lookAhead( match ),
      size = ( match === "@" ? 14 : ( match === "!" ? 20 :
      ( match === "y" && isDoubled ? 4 : ( match === "o" ? 3 : 2 ) ) ) ),

},

RCA

Updating jQuery UI from v1.9.2 to v1.13.2 changes the behaviour of getNumber function which extract a number from the string value.
The issue was also observed when switching to version 1.12.1

changing
v1.13.2
digits = new RegExp( "^\\d{" + minSize + "," + size + "}" ),
to v1.9.2
digits = new RegExp('^\\d{1,' + size + '}'),

will fix the issue.

Missing number at position 5

Link to test case

Start at the dateRange parsing path and inspect the getNumber function, comparing its behavior between jQuery UI 1.9.2 and 1.13.2. Reproduce the Magento admin date-range case and verify that selecting a from date preserves the to date without producing “Missing number at position 5”.
