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.
I have no problem with this.^ The week starts with Monday, not Sunday, as far as I'm concerned.
Just a suggestion in the Sabre: Fares/DotRes screen, I would like a date choosing window for the Return date.
