Nanobreak is typically a very short, i.e. overnight holiday, preferably somewhere quite exotic, which is becoming increasingly popular amongst people in the UK who want or need a holiday despite the credit crunch¹ and despite having very little free time.

Nanobreak（纳米假日）指在居住地以外、颇具情调或迷人风景的地方度过的一个短暂假日，这种假日很短，通常都只在目的地逗留一晚。在那些饱受信贷危机困扰，也少有闲暇时间，但仍然渴望假期的英国人当中，纳米假日越来越受欢迎。

For example:

There has been a 29% increase in the number of UK holidaymakers searching for nanobreaks over the past year.

去年，英国度假者中搜索纳米假日的人数增加了29％。
