Maybe you and I have the privilege to turn off computers for almost a week without a negative effect, but not the majority of the world, everything uses a computer to operate and coordinate.
Think about food production, aviation, shipping, sailing... And much more at both small and big scales.
Wait. In fact, if you weren't born on 01-01-1970, you can't be Time Druid. Sorry.
Well sonnie-boy, listen up... it all started on 01-01-1970...
Kodak used to run on this calendar.
> having one or two days per year which are part of no month is stupid
which I've cleverly circumvented by adding almost a while week. I believe in this case the stupidity overflows and it becomes a good plan again.
All years were 12 months of 30 days plus 4 extra days of summer (Sumarauki in Icelandic), making the year exactly 52 weeks. Leap years had one extra week added to sumarauki making it a total of 11 days and leap years exactly 53 weeks. This has the benefits that each month starts on the same day of the week (e.g. the first day of the first summer month (Harpa) is still celebrated in Iceland and always lands on Thursday).
> There is no special numbering of the years used in the Icelandic calendar, so the year may be omitted or the current Gregorian year used.
It is hard not to imagine a day in Sumarauki as being sort of magically timeless.
Then we can elect some druids or whatever to arbitrarily, at the start of each year, define which dates the seasonal borders will land on. Events which are truly dependent on weather can be defined in terms of "Days after the season starts."
Or we could define a 5.5+-.5 day holiday between the beginning and end of a given year. Those days will be declared to not belong to any year. We will turn off all our computers for those days, and pretend they didn't happen. If you are born within them, you get a special hat or something.
