What is it with Nanditha's birthday??

Nanditha and I share a common superstition, that my 'life' undergoes a complete change after her birthday - which is on March 14th. So it goes like this - until march 14th, some things happen, and then, after that, something happens, and happens abruptly, which changes a lot of things - for better I mean :D
Well - the 'logical' reason would definitely be that march happens to be the end of a financial year, and that most things end/begin in march; but I'd like to believe otherwise.
Well, looking forward with greater trepidation to next winter!!!
