PT7.S4.Q19: Been trying to get a complete answer to this question for months...

My understanding of the stimulus is that since 365 isn't exactly divisible by 7, that leaves an "extra" day which causes the calendar to shift forward by 1 day every year and the author proposes to change that by removing that "extra" day and making it a sort of twilight zone where it doesn't fall into any year so we are left with exactly 364 days which means that January 1st and any other date will be on the same day each year. The part I am baffled by is what exactly happens to those "extra" days? Are they shuffled in before January 1st? If December 30th and 31st still exists, are they still part of the calendar year or do they fall in that twilight zone? If December 31st is the last day of the year wouldn’t this be the “extra” day in the first year?

@Ashley2018 It's swapping between the concept of calendar date "labels" (e.g. "Dec 31") and weekdays (Sunday-Saturday).

The stimulus is suggesting that, if a year doesn't end on a Saturday, there would be some "unlabeled" weekdays between the weekday the year ends on, and the following Sunday, which would become January 1st.

So if a year ended on a Thursday, there would be two "unlabeled" calendar days in between the year-end calendar date label and the next year's "January 1st".

This would cause issues for people that count days sequentially, since that final week of the year could have more than 7 consecutive days when you include the "phantom" weekdays with no date label attached.

Hope that makes sense/helps!
