I don't really understand what you mean. Where do you get two hours?

See below in bold

Okay, here's my riddle. Don't know if it's good, but I confused myself when making it, so it may at least confuse you, too But I'm afraid it's too easy for you.

Imagine you meet a weird guy with his really cool plane who just landed in your backyard to wish you a happy new year and brag about how he started it.

"When I started the party, church bells rang to greet the new year. One hour later, I was watching the fireworks on the beach. It looked so awesome, with everything reflected by the sea! But the sun touching the horizon another 11 hours later was even more spectacular just by itself. After two hours, I was sitting in the sun, enjoying all the light. I decided to sleep for a while and then visit a beach again, where I arrived after 12 hours, that is 26 hours after everything started.

I guess you wonder what is so great about all this. Well, at every time I mentioned, I was at the dawn of the year, 00:00 01.01.2012 local time. Easy with a plane, you may think. But I tell you one more thing - All that time, between two subsequent places, I did not move in west or east direction by more than the W-E distance between the first two positions, which was 5°. Remember, a time zone is 15° wide. There wasn't even a time zone line between those first two places.

So, now, can you tell how I did this?"

24 hours is a day 26 hours missus 24 hours equals 2 hours

Did you go either north or south directly over one of the poles?  If you did, you could travel half-way around the world without traveling east or west at all.

[Giogio]

Yup, that is part of the trick. \o/ Can you explain the 26 hours too?

If nobody answers that until tomorrow this time, I'll just post the answer and give victory to c-square - It's already been too long. But I sorta like the answer, so let's see 

@ sstimson: every time mentioned (church bells, firewors, sun touching sky, sun shining, beach) translates to 00:00 local time, and the difference between first and last time (as you see) is 26 hours. Is that what you meant?

[sstimson]

I think I might be best to wait, because as I see it and I think I can prove what I think your thinking will not work as I see it. but one last question. Is the local time at the points you mention 00:00, if so then you are going to be proven that will not work.

What the hey?

Spoiler:

start Church bells 0:00 1-1-2012
one hour later                    1:00
staying for 11 hours         12:00
sunning 2 hours               14:00
waiting 12 hours                2:00 1-2-2012
If you move between the time you sleep then it looks like this
start Church bells               0:00 1-1-2012
one hour later                    1:00
staying for 11 hours           0:00 (Move back 180 Degrees)
sunning 2 hours                 2:00
waiting 12 hours               14:00 (Move back 180 Degrees) 1-1-2012

Here is your problem. unless you are in orbit and are moving faster then the sun, then the sun WILL go around at least once in 26 hours. I do not believe you are allowing time travel which would be necessary to do your puzzle. IF you do as C-square suggest maybe you can stay the same day, but you must count the time to move from point a to point b. You are possible cheating by not counting seconds but as i see it while the same time 0:00 as far as minutes and hours at one location will be true, you will use at least 5 seconds and the time at each location will not be the same as the starting point. You are still entering different time zones even with going over poles at a day plus real time must happen. But if your local time is the only time you are using then indeed you might be able to make five stops and stay in the same minute. However time is not stopped and the end time will be later then the start time even if only a few seconds.
Put it another way your local time at start is 0:00:00 . First stop their local time should be one hour later or 1:00:00 but using your start location time should be 0:00:01 if it only took a second to go to the first place. You made 5 stops so start location would be 0:00:05 if your complete trip took 5 seconds.

So we get this
Location                     Start time                     Location time

Church Bells                0:00:00                        0:00:00
Fireworks                    0:00:01                        1:00:00
Sun Rise                      0:00:02                      12:00:00
Sun at highest point   0:00:03                      14:00:00
Beach                          0:00:04                        2:00:00

[c-square]

Yup, that is part of the trick. \o/ Can you explain the 26 hours too?

No, I can't.  Even if you started at midnight just west of the international date line (say, in Samoa), and ended just east of the international date line (say, Attu Island), I still think less than 26 hours would have passed between midnight at the first place and midnight at the last place.

You got the starting point right \o/ The ending point is a bit too far in the west, but you got the right idea here.
One last hint, remember this sentence:

There wasn't even a time zone line between those first two places.

Also, wikipedia may help a lot.

*grins broadly* The riddle seems to work after all 

Now back to answer sstimsons message...

[Giogio]

@sstimson: Sorry, my session just was timed out when I tried to send the answer to your post, so it vanished  :|

So, here's the short version:
I'm sure it is possible. No time travel. I calculated the distances now, and with travelling a bit above speed of sound, you have time to travel AND enjoy midnight at every point.
I don't get the 5-seconds calculation you made. As I wrote, several hours pass between the points. The times are exact, to the millionth of a second (and more if you want). You don't need to cheat for seconds. And it does not matter how far the sun gets around in this time - what matters is what the clocks show at the respective points.

If you want to say so, then I be glad to prove you wrong. You basically you can not got east or west, leaving north or south.I be glad to wait and then prove your thinking wrong. but I start with the first two.

Church bells start at 0:00:00 stay you stay for five minutes you then leave so local time is now 0:05. you travel for say 50 minutes. You then watch the fireworks at your new location. The time at your starting location is now 0:55 even if the time you are at is 5 minutes until 0:00. Lets say you stay for 10 minutes. Your start location time is now 1:05 and the place you are at time is 0:05. You now travel for say 10 hours and 45 minutes. That makes the start time 12:50 and the place you are at 11 hours away (1/2 around the world) time would be 10 minutes until 0:00 you stay for say 15 minutes. your start time is now 13:05 and your location time 0:05 you travel for 1 hour 45 minutes. Your start time is now14:50 and the location time is now ten minutes to 0:00 but you are getting close to the Internal date line. You stay for 20 minutes ( 15:10) then travel for 11 hours 45 minutes, meaning you closed the date line . your start time is now the next day at 3:55. As you have gone around the world once, you are forced to either be the same day but three hours later on the next day at 0:00. Your idea might work for those 4 places, but the fifth, it breaks down. Your problem is time. It takes time (in this case 26 hours) so if 26 hours have passed then the same day and same time no longer works. If you travel west at the same rate as the sun, then you can get an theoretical inifity number of times where you and 0:00 happen, but you must keep moving for that to happen. Facts: the Earth speed  is abut 30m/s. Sound speed is 340 m/s. Earth's Circumference at the Equator: 40,075.16 km  But you need to understand that even if you went around the earth 6 times, that does not mean that 6 days have gone by. the the time it took you to do this has gone by. If you really wait for 26 hours then in real time 26 hours have gone by no matter where you are. You trick might partly work (4 times as written), but in absolute time, that time can only happen once. I will be waiting to show you why what you are saying does not work.

time to go around the earth at sound speed is d=r*t, t=d/r D=40075000 m R=340 so T=117868 Seconds which is 1 day 8 hours 41 minutes 26 seconds. Let me put it another way. Time to go 1/24 around the planet is 1669792=d t=4911 seconds or 1 hour 21 minutes 51 seconds means at the speed of sound it takes more then a hour to go from one time zone to the next. East west
d northsouth =40,008000 t=117670 or 1 day 8 hours, 41 minutes, 10 seconds

see your problem yet?

[Giogio]

Well, as promised, here's the solution:

Reference time will be UTC. As c² said, the trick is starting off near the international date line, then going south (over the south pole), then returning to the date line (this time more to the north so that you get on the other side of it).
See: http://upload.wikimedia.org/wikipedia/c ... e_Line.png
As you see there, Samoa and Tonga are both in the +13 UTC zone; Baker Island in the -12 zone - only 25 hours. So what is missing?  The fact those guys have summer down there at the moment. And, some of them, use summer time. Samoa does, Tonga does not  So Samoa is actually at +14 UTC. (http://en.wikipedia.org/wiki/Summer_time)

That means: (Sa was 31.12.11, So = 1.1.12; dst = daylight saving time)

Sa 10:00 UTC - Samoa (dst), +14 UTC, 172°80'W
Sa 11:00 UTC - Tonga (no dst), +13 UTC, 178°55'W (Minerva Reef)
Sa 22:00 UTC - Sanae IV station (no dst), +2 UTC, sun touches horizon, 2°50'26''W
So 00:00 UTC - near south pole, +0 UTC, sun shining, 0°W
So 12:00 UTC - Baker Island (no dst), -12 UTC, 176°28'W

The longest travel is about 1/4 around the globe, that is 10000 km, speed of sound is 1236 km/h, so ~ 8 hours flight (from Tonga to Sanae IV for example) - seems to be enough time.

So if you have any logical complaints about this, tell me 

c-square, it's your turn!

I'm looking for the whole sentence.  It shouldn't be that hard (especially seeing how quickly some of my previous ones were guessed).  Since it's been a few days, I'll give a clue:

Just a small, nice one:
You have a wall and two points A and B. Now you're supposed  to draw a straight line from A to the wall, then to B - and it is supposed to be the shortest possible line. What is the easiest way to do it?

Something like this:
