In Czech Republic today (24th) is traditionally Christmas Day, and I should have been there now, but thanks to a certain low cost airline my flight on 22nd got cancelled and the earliest alternative was on 26th.
:(

So my change of my itinery

(1) Christmas Eve will be on Boxing Day
(2) Christmas Day will be on 27th December (Christmas Dinner with my partner and her mother) and also on 3rd of January (Christmas Dinner with my partner and her grown-up kids!)
That means that there will be two new years/new years eve.
(1) The traditional new year which will last for 2 days before reverting back to 2009 on the 3rd of January.
(2) As 3rd of January will be reverting back to December 2009, then New year will also be on 5th/6th January in time for our flight to UK on 8th January, at which point normal order will be restored.

This works out well for me as the 3rd-5th of January will be in 2009, so I won't have used 3 days of my leave entitlement for 2010. The upshot, however, is that 2010 will only have 362 days, the shortest year since the change to the new calendar. I am just glad that I will be on holiday when all this is happening and I don't have to pursuade my clients, and the UK Goverment (HMRC) to work around this!
