Annoying bugs

When entering the following key phrase: September 1752

Wolfram Alpha currently produces a calendar for September 1752, without the day numbers: 13, 14, 15, and 16.

This is at variance with the Unix: cal 9 1752

command which eliminates day numbers: 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13

and is in keeping with the transistion from the Julian calendar and changes to the Gregorian calendar made by Pope Gregory XIII in 1582.

This is a serious bug because any computations of the number of days between two dates that contain the days of September 1752

will be off by 11 - 4 = 7 days.

Note also that the key phrase: which months have 26 days

Finds no input interpretation and suggests a rewording: months have 26 days,

which finds zero, but changes the number 26 to 27 as in

number of months with 1, 2, ..., 27 days

The result in parenthesis states: In the Gregorian calendar, month lengths are always 28, 29, 30 or 31 days

which is incorrect for September 1752.
