If I asked you, "How long is a day?" I think most people would answer, "24 hours." Some people might ask, "What do you mean when you say a day?" That's a valid question, because I could mean a solar day or I could mean a sidereal day. A solar day is the length of time between when the sun reaches its zenith until the next time the sun reaches its zenith. (That's 24 hours.) A sidereal day is how long it takes the Earth to rotate 360 degrees about its axis. Like, if you were watching Earth through a telescope from Betelgeuse (or any far away star), how long would it take from when you saw the big island of Hawaii at the very center of your telescopic view until the next time you saw the big island of Hawaii at the very center o your telescopic view? That's a sidereal day, and it is about 23 hours and 56 minutes. The reason it takes us more than a 360 degree rotation to get the sun back up to its zenith is because the Earth is also orbiting the sun at the same time it is rotating.

But the question "What do you mean when you say a day?" is even more valid. I am about to say something that sounds crazy, but it is true. I just experienced a 35 hour day. You think, "That's not possible, Erich!" But it is. It has to do with what I mean by "a day."
You know about "Beware the Ides of March," right? The Ides means the fifteenth of the month, and it was a bad day for Caesar. Usually, March is the only month in which we even discuss the Ides. But I just had a very special Ides of June. Special how? It was the 35 hour long day I mentioned before.
Our story begins on June 14, but it begins at 11:40 PM. That's when the plane transporting Alrica and I took off from Bangkok, Thailand. Twenty minutes later, it was the beginning of June 15, the Ides of June. And we were in the air. And when we landed, in Frankfurt, Germany, it was 6:15 AM. Now you might think, oh, you spent about six and a half hours in the air. But no, we spent eleven and a half hours in the air. Yes, it was only six and a half hours different on the clock, but Germany is in a time zone that is 5 hours behind the time zone of Thailand.

| Old Town in Frankfurt, Germany |
Our flight left Frankfurt at 1:20 PM. (Well, it was scheduled to leave at 1:20 PM, it didn't actually leave until after 2 PM.) This meant we were scheduled to have about a seven hour layover in Frankfurt. We took advantage of it and caught a train from the airport into the city. We walked around, saw some sights, ate a bratwurst and an apfelstrudel (apfel is the German word for apple), and returned to the airport with plenty of time to go back through security to reach our gate.

| Cathedral of St. Bartholomew |
Frankfurt was fine. It didn't really dazzle me. But it has a very cool looking old town. I really liked that. But a lot of the old town isn't that old. During World War II, most of that area was devastated by British bombing. The one exception is the Cathedral of St. Bartholomew.

| Look, a restaurant in Frankfurt with my name! Well, my first name. |
The cathedral is quite striking. It has these exceptionally tall archways. It also has a very involved organ. It's a pretty building. Inside the building, there is a photograph of the neighborhood just after World War II. And you see this one building, the cathedral, standing tall, surrounded by the blown out wreckage of everything else around it. I don't know if the British somehow planned their bombings to spare it because it was a cathedral or if it was random luck. (If you prefer a supernatural explanation, go for it. I don't subscribe to that explanation, but more power to you if you do!)
We didn't end up boarding our plane until 1:20 PM and as I said, we didn't take off until after 2 PM. We landed in Newark, New Jersey, USA at around 4 PM. Again, this was not a two hour flight. It was an eight hour flight, but we changed six times zones.
We had a not-quite-five-hour layover in Newark. We did not go into the city to explore. As some of you know, long ago, Alrica and I lived in Jersey City, New Jersey and then in Edison, New Jersey. We lived in Edison when our son was born. So we've been to the Newark Airport many times before. And we've been to Newark. Not only was there not enough time to go play around in Newark, there was no desire to do so. I've been, and it isn't that noteworthy that I felt it was worth the effort.
Let me say, I was unimpressed with the airport in Newark. Yes, I had been before, but it was never as a transfer. It was either my start or my end destination. This time we flew into Terminal B, went through passport control and customs, and then we had to get to Terminal A. They have an AirTrain that goes between the terminals. You catch it right there in Terminal B. But when you arrive at the Terminal A stop, you are not at Terminal A. You have to walk from where the train lets you out to Terminal A. Well, you can either walk 12 minutes to the terminal. Or you can walk 4 minutes to a road where you can stand around waiting until a shuttle bus arrives, picks you up, and drives you the rest of the way to terminal A. Either way, not impressed.
We flew out of Newark at 8:45 PM on a flight that was close to three and a half hours long. We landed in Fort Lauderdale, Florida. This time, there was no change of time zones. But our landing time was 11:59 PM. The very last minute of June 15.
But now think this all through. We were in the air at 12:00 AM when June 15 began. We then spent about 11 hours getting to Germany. We spent about 7.5 hours in Frankfurt. Next was another 8 hours on a plane to Newark. Then around 5 hours in Newark Airport. And finally, close to 3 hours flying to Fort Lauderdale landing at 11:59 PM. All on June 15! But if you add that up we have 11 + 7.5 + 8 + 5 + 3.5 = 35 total hours all on June 15! The Ides of June lasted 35 hours for us.
How is this possible> Because, of course, we transitioned through 11 time zones during those 35 hours. The normal 24 hours plus the bonus 11 hours from traveling through time zones while still on the same calendar day gives us a day that lasts for 35 hours.
So here, this is neither a solar day nor a sidereal day. It is a particular date on the calendar, June 15. And the honest answer to "How long is a day" can legitimately be "35 hours." What's more, along with that, you get the special bonuses of jet lag, a confused stomach because it never understands when you are going to eat your next meal, a cramp in your neck from sleeping in uncomfortable airplane seats, and a sore bottom from sitting in those same seats for way too long.
But hey, it's worth it just so I can ask, "How long is a day?"
