Nah, doesn't work like that in practical (spoken) Finnish. Someone born in 1975 would be "seiskafemma", someone in 1984 "kasinelonen" and so forth. Even spelling the whole word out would be along the lines of "ysitoista seitenviis" (19 75). No-one would ever say "yksi-tuhat..."

Ghosting obviously sucks. But, I challenge the OP to post a link to their code here. Hardly anyone on this planet writes 2Kloc of fresh tested, error-free ("ironed out the edge cases") code in 6 hours.

Happy to do a free code review if it's in one of my native languages.

Want to tell what B and X stand for here apart from random consonants?

What does "apply for HN" mean in this context?

To get any meaningful results, we'll need a decent sample size. Magnitude 7.0+ quakes in Japan are a fairly rare phenomenon, occurring 1-2 times per year. If we pull out a somewhat larger data set of 136 such quakes in the last 100 years (https://www.volcanodiscovery.com/earthquakes/japan/largest.h...), we'll notice that the quakes are fairly evenly distributed between the months.

The mean is (of course) 8.33%, and the standard deviation 1.91%. All months fall within 2 standard deviations from the mean (March is highest at 11.62%, followed by Feb at 11.06%, Jun 10.51% and Nov 9.76%). So, nothing particularly interesting to see here. Also, if we do the same "three-month window" analysis you did, the winner is February (with 30.68%, somewhat higher than the expected 25%).

Probabilities and statistics don't work like that. Between 2011 and now there's been loads of earthquakes in Japan, in most months, many stronger than 7.0.
