So, my crazy brain went on a side quest and realized there are not 52 weeks in a year. There are 52.14285714285714. Leap years are 52.28571428571429. Hello from my weird brain It doesn’t deal in integers

This is why the calendar would have been much better suited to 13 four week months! You still end up with that trailing digit stuff after the decimal, but at least the months would all be the same length. It would make calendar printing so much easier if the first of every month was the same day of the week for a year!! One month would have one (or 2 in a leap year) extra day(s).
PS. I always found it fascinating than not all century marks are leap years… In the days before computers and incredibly accurate timepieces how the f*** did they figure that out?
Ok… so my weird brain just noticed that in either a normal year or a leap year, the decimals for both have two 14s, two 57s and two 85s. There are three 28s and leap years end in 29. Which is the number of days in February. I’m going to stop looking at numbers for a bit Sorry, my brain and fingers don’t always consult me before they start working without me
A friend and I were recently discussing monthly and annual salaries.
He kept saying his monthly salary was $XX times 160 hours.
I kept telling him that a month is 4.3 weeks, not 4 weeks.
He continued to keep ignoring that fact in his calculations.
@Cerridwyn@kittykat9180 That’s why some people pay down their mortgage by making a payment every 2 weeks. It kind of feels the same but every year you’ve squeezed in an extra month of payments.
@Cerridwyn@kittykat9180@therealjrn I did the biweekly mortgage thing on a house almost 4 decades ago and paid off a 15 year mortgage in 12 years, because of a faster-declining principal for the compounded intrrest to hit. That saved a BUNCH of interest! Funny thing, GMAC, the finance company, suggested it. They were the best mortgage lender I ever dealt with. The worst, Wells Fargo whom my original financer on a different house sold my mortgage to, offered me autopayments IF I paid them a several hundred dollar upfront fee. (Charging me to save them money…; f off! Later they made it free.)
@Cerridwyn@kittykat9180@therealjrn That has the same effect as if you invested $125 monthly into an annuity at THEIR compound interest rate and then withdraw to pay off your mortgage. Smart move.
Payments over time can work for or against you with compounding.
@phendrick
I have a very low interest rate, so honestly, the money would probably be better invested.
But I invest too. It gives me the warm and fuzzies to know that I’ll pay off my house sooner and pay less interest.
It doesn’t deal in integers 
Also, I’m 54 so that means there are eight weeks that either do or do not exist
Did I mention my weird brain

But the real kicker is that it’s not the apparent year, but rather the sidereal year, that drives the positioning of the leaps.

@kittykat9180 best to do 2080 hours in the work year. that is what most companies use to calculate salaries

@Cerridwyn @phendrick @therealjrn
He was already making it complicated enough, at some point I had to just let him do his thing.
I don’t think my mortgage servicer has it available to set up auto pay every two weeks. But I do pay an extra $125 per month onto the principal.

@kittykat9180 I always like thinking “my job pays me like there’s 4 weeks a month, but everyone else charges me like there’s 5 weeks a month”
