      Ah yes. My favorite day of the year. December 3rd is when I get all hot and bothered.

      No legend makes the colors and numbers pretty pointless and the whole thing unclear.

      OK, this data set has a bias in it

      The drop in births on holidays is because people are scheduling C-sections, and doing it so as to not interfere with the holidays

      So you cannot use that data and count back 9 months.

      It’s always fun to compare this with data from the southern hemisphere to see if the Oct-Dec bump is weather-driven or holiday-time driven.

      This is hilarious to me since I’m currently pregnant, estimated delivery date is the first week of September and I likely conceived around December 6th. I wonder why it’s so common to conceive in December? Are we all just cold and bored?

      I like how there’s a small bump of people getting conceived on Valentines Day followed by an entire frigid week with less sex than usual.

      As someone born on April Fool’s, I feel vindicated that my lifelong suspicion of a worldwide conspiracy of parents trying to save their kids the “embarrassment” is actually true! I actually love it, it’s a memorable birthday on a day when people are silly!

      The colobar is not symmetric. Positive values are more intensely colored than negative values.

      So Thanksgiving to Christmas time is prime time for sex? Is that what I am reading?

      Is it also because people have holidays at that time?
