[quote="ostarella"]Well, obviously the timing of release, promotion, subject, etc have much more to do with sales increases/decreases than the month - but if, as the OP stated, you're trying to get some handle on why sales were up one month versus another, industry statistics would be helpful. It's one of the variables to track, along with what promotional activities you had done, distribution, competition, etc. It's what retailers do, and even though one's publisher does that, it certainly can't hurt to have some understanding of it oneself.[/quote]

seek and we will find
more books are sold on sunday than other days
more books are sold at 1&2 pm than other hours
more books are sold in last 3 days before the last day of the month
they drop way down on the last day
you can see month by month here

https://www.statista.com/statistics/207468/monthly-retail-sales-of-us-book-stores/from the first source i found
https://lunch.publishersmarketplace.com/aap-statistics/most adult books were sold in november
followed by october and then december
jan to july are lowest and about equal
in august they go up aug and sept
and peak in october
so what is anyone going to do with that information
if your book is not out there it wont sell at all
and if it is then it depends on your promotion efforts
you wont suddenly start selling cause more books are sold in october and it pulls yours along for the ride
