And a Happy New Year!

I read but I forgot.

How is the easter thing related to this thread?

All I meant is Oct 31 = Dec 25

The same thing.

To be clearer, I would have to know what you meant exactly.

It means that (8^1)*3 + (8^0)*1 = (10^1)*2 + (10^0)*5

Hmmm, that is a sufficiently bizarre idea to make everyone misunderstand you. Wunderbar! I predict you will be a great mathematician.

I had thought that it was a joke along the lines that the shops already have Christmas things etc etc...

Yes sorry I didn't understand the first post either.

How about this for a puzzle: Which is the shortest length of time from today: Next Easter Sunday or the previous one ?

I would love a puzzle but I'm not sure what ester is. Maybe the weekend of the good friday? o.O

You are right. I can not speak for everyone.

I was hoping when I wrote that that the two lengths would be near to being equal, but they are not that close in fact:

(1) 31st March 2013 to 31 October 2013. How many days is that ?

(2) 31st October 2013 to 20th April 2014. How many days is that ?

To be frank the only difficult thing about my puzzle is that silly mistakes and off by one errors are very easily

made with those. A computer programmers puzzle might be to write some code that can solve things like that....

Anyway according to my reckoning.... (well I won't tell you the answer, but it wasn't as close as I had thought).

On what day or days this year would that have been an awkward puzzle? (ie half way between two Easter Sundays in the UK.)

I am getting 9th and 10th of October 2013 for the mid-point. (ie: midnight after the 9th October)

Okay how about this one:

Does British Summer Time (BST) and Greenwich Mean Time (GMT) considerations make any difference to the

exact mid-point between the end of Easter Sunday of 31st March 2013 (BST) and midnight immediately before

the start of 20th April 2014 in which we are in GMT technically ?

Start of BST in 2013: Early hours of 31st March 2013 (clocks go forward one hour)

End of BST in 2013: Early hours of 27th October 2013 (clocks go back one hour)

Start of BST in 2014: Early hours of 20th April 2014 (clocks go forward one hour)

Do we have to add half an hour, subtract half an hour, or is there no change, or is there a different adjustment ?

It might be best to think of it purely in GMT converting the defined start time into GMT start time for the 2013 Easter.

I would not swear to this as correct, but personally I think that the mid-point is the 10th October at 30 minutes past midnight,

that is after conversion back to BST which is the correct format of the time zone on the 10th October. (???)

In GMT 11:30pm on the 9th October if we were in GMT which the UK wasn't on that date of course.

It's a good job I didn't involve any space time distortion physics really !! That would have been really difficult !!

Joking aside I was thinking of making up an example of someone doind a mid point between two countries with

two time zones, but the same sort of event in 2 years... Anyway I can't think of another dec / oct thing apart from

my observation that:

10 in decimal = 8 + 2 = 8 is 10 in oct and 2 units = 12

So convert using the function of decimal into base 8 and the month of October nicely converts into a "12".

This is the inverted way round to the original joke of: 31 Oct = 25 Dec

so it does not quite work.
