All date-related formats throughout the KVS Tool have been recently brought into conformance with the international conventions, used in the travel industry, as well as the ISO standard. This includes weekday numbering (1=Mon, 2=Tue ... 7=Sun), so the calendar layout is now consistent with this convention.
Wow, that's a real shame. It's all well and good to 'comply with conventions' but for me this is a definite usability decrease. This tool is now much harder to use for me -- every time I look up anything.
If this were a configurable setting (even a hidden registry key -- this is only one UI element after all), that would be a definite improvement.
I have to say despite my general ^ for this tool, a great big

for the unannounced, undocumented, user-hostile change.
Thanks,
