It would be great if all valid "D/M" date patterns are accepted as dates. This is not true for 1/2, 1/4, and 3/4 which seems to be handled by the autocorrection stuff.

Steps to reproduce:

1. Make sure that "D/M" is listed in "Tools/Options/Language
Settings/Languages/Date acceptance patterns"
2. Try to enter the following dates:   1/1,  1/2, 1/3, 1/4, 1/5, 3/4

Result: 1/1, 1/3, 1/5 are interpreted as dates but 1/2, 1/3, and 3/4 are replaced by the related autocorrect strings.

Expected Result: All the values should get interpreted as dates

Motivation: For normal users (my wife), it is quite surprising that only the three variants 1/2,1/4, 3/4 are handled different way ;-) IMHO, dates are much more used by Calc users than fractions.
