#How result is calculated

DANG. Absolutely cold-blooded.

It's the very first day of 2025! Do you know what that means?

Very serious calculations are back!

In 2024, I read 164 books. After the very serious calculations, it amounts to 54% written by women!

This result is much lower than the previous years, but there is a very simple reason for that: I caught up on a lot of the English and French literary canon... which mainly consists in books written by men.

As for the other calculations: 40% of my five-stars ratings were written by women (that's 2 out of 5 so yeah.) and 100% of my one-star ratings were written by... a man! (there was only one this year, which is strange enough to be noted)

Feel free to reblog this with your own very serious calculations!

The Hebrew Calendar

(Because I'm being stupid)

It is well known among Jewish circles that our calendar is lunisolar, meaning it adjusts to both Lunar months and Solar years. What is less well known about that is the exact numbers related, apparently. To be fair, a large part of the calculation is complicated to a frustrating degree, especially since all the sources I could find use a geocentric astronomical model that was popular 900 years ago. So I'll keep away from that as much as possible.

The length of a Lunar month - the amount of time it takes the moon to go through a complete waxing and waning cycle - is traditionally 29 days, 12 hours and 793/1080 of an hour - a little over 29.5 days, which is why about half the months in an average Hebrew year are full (30 days) and the other half are lesser (29 days). Since synchronization of weekdays is also important, we'll note that there are 1.5 + 793/(1080*12) excess days in a month. Remember that.

Now, the length of a Solar year is about 365.25 days. Only it's not, because it's more like 365.2422. This is what made Pope Gregory skip four days and rearrange the whole system - but we Jews weren't lucky enough to have someone notice. I mean, the Talmud does have two different estimations IIRC, and one of them is slightly more accurate, but it changes very little. So, if we believe the calculations presented to us, you'll find that 19 Lunar years of 12 months each, with seven years that have an additional month, add up to about 19 Solar years. Due to how this math works, I'm going to calculate it separately for days, hours, and Ḥalakim (one in 1080 in an hour, about 3.33 seconds). The number of months is in the end 235 (19 times 12 plus 7), so:

793*235=186355. To add what's left to the hours: 186355/1080=172(595). I have used a calculator for this and I'm not ashamed because those are large numbers to work with. So, 595 Ḥalakim, with 172 hours to add to the next level.

12*235+172=6*470+172=2400+420+172=2992 hours. To add to the days what's added: 2992/24=124 (16). So, 16 hours, with 124 additional days.

29*235+124=20*200+20*30+20*5+9*200+9*30+9*5+124=4000+600+100+1800+270+45+124=6815+124=6939 days. No more questions. Our numbers are, then: 6939 days, 16 hours and 595 Ḥalakim.

Now to the other side: according to Google, a Solar year is 365 days, 5 hours, 48 minutes and 46 seconds. To convert the minutes and seconds to Ḥalakim: there are 18 Ḥalakim in a minute, so 48*18=6*8*6*3=3*2*3*2*2*2*2*3=3^3*2^5=6^3*2^2=216*4=864. In addition to that, one Ḥelek is three and a third seconds, meaning there are almost 14 in 46 seconds. Making it all 878 Ḥalakim. So:

878*19=800*10+800*9+70*10+70*9+8*10+8*9=8000+7200+700+630+80+72=15900+782=16682 Ḥalakim. To find how many additional hours: 16682/1080=15(482). So, 482 Ḥalakim, with 15 hours to add.

5*19+15=110, pretty straightforward. To find the excess days: 110/24=4(14). So, we have 14 hours, and four days for the next calculation, which is:

365*19+4=3000+2700+600+540+50+45+4=6890+49=6939 days. So, 19 Solar years are 6939 days, 14 hours and 482 Ḥalakim.

As you can see, it's the exact same amount of days, which basically serves our purpose! There are 2 hours and 113 excess Ḥalakim in favour of the lunar months. If you want it in minutes, it's about 6 minutes and 16/17 seconds. All in all, not too large. But. Every 12 cycles, the difference gets larger than a day. 12 cycles are 228 years, so it's a while, but by now it's been 1700 years since the calendar was based on calculations instead of witnesses. So by now, the difference is about 7 days. Only... Not necessarily. Because the Hebrew calendar also has to account with the days of the week, which is where our previous point about the one day excess becomes relevant. Kind of.

Look, all of that - most everything mentioned here - comes from Hilchot Kiddush HaḤodesh by Rambam. And he gets much more into the math, which I don't have the energy to do now, and he has a whole awful lot of calculations on how you decide when Rosh Ḥodesh needs to be according to the math and when Rosh HaShana or Pesaḥ will fall in the week etcetera. Due to this kind of thing, the amount of days in Ḥeshvan and Kislev aren't consistent between the same year inside a 19-years-cycle, and thus some of them are shorter and cover said difference. Maybe. Maybe some are longer and create an even worse difference. But our calendar wasn't built around the accurate calculations, it was built on the 0.25 assumption that the Julian calendar was built for. Which is another reason why we might be out of sync with the Gregorian calendar in the long run. In the short run, due to 19 not being divisible by 4, the leap day can disturb things. So while in theory every 19 years the calendar resets and all the Hebrew Calendar days are the same in the Gregorian calendar as they were 19 years ago, in practice leap days can get them out of sync.

If for some reason you want to calculate the next average moon renewal, you should know that the first one was during the Hebrew year 0, at monday, 5 hours and 204 Ḥalakim. This is for the first ever month of Tishrey, currently considered the first month of the Hebrew Calendar year. We are now in the middle of the 5th month, year 5785 from this particular day. The rest is multiplication and addition based on numbers already mentioned here. Have fun!

hour and a half unpaid overtime I think that's a new record for me. on a day where I was supposed to have no overtime no less. funny how I only have 3 of those this month and the 2 so far I've had to work overtime anyway 👍

"why don't you take your full stimulant dose during the week"

because if i take it full blast every day it stops working so i make sure to take breaks on days that don't matter, which are days that i work, so i can focus on days that do matter, which are days that i do not work next question

7,876... idk what to say. I wrote and wrote until the creativity voice went quiet for the day. Let's hope I'm this productive tomorrow!

𝐅𝐈𝐒𝐇 𝐌𝐎𝐍𝐄𝐓 - the sacrifice

a knife to your back is your first memory– it will also be your last. you cannot help but let things into your heart, such is your nature. time and time again, however, they hurt you and leave you to rot. but your heart remains open, and you continue to let more in. is it kindness, at that point, or is it sacrifice?

𝐅𝐈𝐒𝐇 𝐋𝐄𝐂𝐓𝐄𝐑 - the final girl

you're very tired, aren't you? thrashing and fighting and trying to survive– it has taken its toll, but that has not stopped you. you'll continue to gnaw and scream and bare teeth until you can free yourself from this mess, even if it means being the last one left. there is rest at the end of this hard battle, i promise you. there is a time when the fight will be over– but fighting is all you know, isn't it?

also. The start of the game forcing u into the genesis comic feels. Very silly. its a tonal jump from the death to like have sudden narration. It shouldve been framed differently idk. Or just. Not inserted into the story. Anyways.

Love the beginning of this game. Setup is so good. I love Jacob and Mirandas intros. Jacob as the one who tells you the truth, who has a moral compass vs Mirandas sole purpose and drive for two years being to bring you back to life regardless of her impression or opinion of you personally.
