The resurrection of the appearance of a star cluster reappearing to view above the Horizon around the winter solstice to be celebrated as a movable Mondayised day for the King does not restrict the loss of productivity to just Friday.
Yesterday I was able to retrieve furniture from a small business following minor repairs.
Now we have a weekly appointment late morning Thursdays that is of considerable benefit to Swmbo so I arranged to pick up the items at lunch time.
The time was set some time ago and it was with a degree of panic when one of the two owner operators of the Small enterprise rang me mid morning to establish the time of pick up as their Business was closing at 12 00.
Apparently it is not a weekend lengthened by adding Friday, it is to begin at midday Thursday?
Then I guess there will be a degree of sudden illness and/or family incidents next Monday, little wonder New Zealand continues to dive into the swamp of destruction.
Is it time to begin agitating for the Celtic Lughnasadh for August the 1st, as there may well be another bunch of immigrants wishing to call up their origins and have a day off.

Does Matariki start when the first star of the Peliades cluster appears above the horizon or the last star of the cluster?
It starts when the first claim to the Waitangi Tribunal appears over the horizon.
It started when Maori academics in the ’90s made it up. Happy Maori Kwanzaa everybody!
