When the Underground runs all night (usually New Years Eve / Day), how are trains numbered? Some trains will run all day, all night, then during the next day. Do they keep their original numbers from the day before?
Also, in the timetable notice, is there any division between the days, or is it shown as one long, continuous day?

I dunno if other lines are the same, but on the District.......
I suppose it's possible, through re-forms and the like, that a train may be out over the full two days....but usually the timetable is compiled in such a way that trains will visit a depot or siding during the two day period:
The all night trains will generally come out at about 11pm on day 1, with the trains that have been running all day on day 1 going to bed during the night - then as day 2 kicks in, those trains that went away will come back out and the ones that have been out overnight will generally stable early in the evening of day 2.
Trains that come out on the second day are shown as shaded in the depot working section of the timetable, and do indeed use different numbers.

Some trains on the Jubilee entered service early on 31st and didn't stable till late on the 1st.

There was an artical in the Jan 02? edition of Underground news about this very thing. I believe on this occasion the longest in service was a C stock that did roughly 46½ hours. Every fact in that sentence could be wrong, however, apart from the duration.

The large majority of Circle Line trains did the full 2-day stint over 2008/09. The majority of H&Cs and Mets (though by no means all) were swapped more or less in the same way as Colin mentions on the District.

I was reading this (just gone) Christmas/New Year Met TTN in bed a couple of nights ago, and I remember that the Chesham shuttle renumbered from 407 to 406 about 3am; the trip counts also reset at about 3am too.

For many numerous reasons, the Tube day will always attempt to begin at 3am, with the previous day having a line drawn under it. Of course there are always days where the previous days business hasn't actually finished before the next day begins.
One area on NYE where the "new day" would be felt to start is in the Signalling Centre at Baker Street. I believe my learned colleague with whom I used to work in the SCC with and certainly myself at some point have mentioned the fact that the computers "dump" the previous day at 3am, and commence loading the next traffic day - with the time inbetween (some 40 or so minutes) seeing the computers more or less incapable of doing anything much.
But as this "new day" started, all trip numbers would once again commence at Trip 1.
As an aside to this, the computers are only able to recognise trip numbers of 2-digits. So even if the computers could handle moving directly onto a new day without stopping, certain problems could be had with trains such as the Chesham shuttle, once the trips reached 100.

Of course there are always days where the previous days business hasn't actually finished before the next day begins. Indeed - every single day Here's an little realised fact: LU operates on a 28½ hour day! A one day Travelcard, for example, bought after midnight is valid until 0430 the following day. If you had a weekly, monthly or whatever, and it's valid until say Friday.......you can actually use it until 0430 Saturday morning. Of course LU doesn't run trains all night, so the practicality is limited [in LU terms] - but of course there are night buses.

National Rail ticketing operates on a similar basis... And there are a handful of routes you can make good use of it on ...

Here's an little realised fact: LU operates on a 28½ hour day! Yes and half the ticketing system (gates etc) works on day 1, with the rest picking up on day 2. It's related to the fact that person A with a ticket for day 1 can use their ticket until 0430, whilst person B with a ticket for day 2 - purchased on day 2 - can use their ticket prior to 0430 (from 0230 I believe). It's very complicated how it does it, and someone showed me once how it does it, but that was some years ago. It may have changed since then, but that's certainly how it used to be. It's one of the reasons why New Year's Eve is opened up with free travel.

Of course LU doesn't run trains all night, so the practicality is limited [in LU terms] - but of course there are night buses. Colin are you sure that's how it works - been a few moons since your booking office days. My experience is the ticketing system works as Metcontrol mentions. The ticketing system has an end of day at around 0230. Any ticket sold prior to 0230 will be dated the day before and as such will only be valid until 0430. However IF you can find a booking office open after midnight (there are a few) then the booking clerk can start either a peak or off-peak TC for the next day and that would be valid. I've experienced more than once an intoxicated member of the public who buys a TC after midnight only to see the wrong date but with no booking office open you can't solve their problem which causes a few "complaints" which has resulted in the Police being called on more than one occasions. Back in my booking office days, always switched off the passenger machines after midnight to remove that problem.

I must admit it has been a while since I had anything to do with ticketing - I guess Oyster has changed things then?

What Colin says mostly applied this New Years Eve, with only a few trains out throughout (reformations excepted) however in previous years a rather larger number were out throughout !
As timetabled District Line trains in continuious service were : 11 D stock and 5 C stock
of which the longest continuious runner was Train 21 at 44 hours 40mins (from 04.42 Upminster dt 31-12-08 to 01.32 Parsons Green 24rd 1-1-09)
closely followed by Train 17 at 44 hours 26 mins (04.55 Parsons Green 28rd 31-12-08 to 01.21 Upminster dt 1-1-09)

Apropos of this subject - would a ticket dated 31 December (i.e. New Year's Eve) be valid on all services advertised as running on that day?

I was refering to the dates in terms of traffic days. Trips after 00.00 are still reffered to as part of the preceeding date traffic day. But I guess that can be confusing. So, yes I was listing trains that stabled in the early hours of 2/1/09.
