To explain the variability in the background data, it’s likely to be because between 2006 and 2020 the days aren’t spread evenly on each date. For 14 years, if each date has 2 of each day, then the data should be pretty consistent, however if you take the difference between Jan 1st and 2nd for example, the distribution is:
Monday 2(Jan 1st) 3(Jan 2nd)
Tuesday 3. 2
Wednesday 2. 3
Thursday 2. 2
Friday 2. 2
Saturday 1. 2
Sunday 3. 1
So it’s likely to all be noise apart from Halloween.
