Birthday distribution December 7, 2007

In my personal observation, I seem to think that more kids are born in the latter half of the year (esp Sep-Dec) than before …. so it would’ve been interesting to see the stats for the year, though I know it’s too much effort.

From the data for 64 of my high school batchmates that I drew up almost an year ago out of curiosity.

Birthday distribution

Thats 28 in the first 6 months, 36 in the latter half. So there, therandomzier, too little data but still some supporting evidence I guess. Treat yourself to what – more frequent blog posts ?

You’re back with the old look! 🙂

Feels like I’m back in the comfort zone. Navigating through the new look was like wading through unfamiliar, new territory 🙂

Even more interestingly, I’ve found out that a good third of the people in my department (theatre) share the same astrological sign.

Scorpio, if you’re curious.

The rest are evenly distributed, but there’s a preponderance of us mysterious Scorpios, for whatever reason. (Which is just to say that we’re a bunch of winter births, as noted above.)
