I said in my prediction post as:

..may occur within next 48 to 280 hours from 04.30 UTC on 5th April 2007.

so it is valid till 16-17th April.

And after analysed the previous quakes history and informed that it may
occur either on 13th April (well fitted in my time frame) or 18th April
(just a day after my time frame). Please note that I have given the
dates well before the occurance. Hence I dont find any mistake.

Also still I am on the learning process and I would like to share whatever
I am learning and that too in advance.
