Just came back from lunch, having conversation with colleague, any planning for 31st December, i mention to bring my girl friend to watch the last sunset of 2009. He told me that this new year eve is Blue Moon event, Hmm.. what is blue moon event, i google it and i found the anwser that i seek. Link 1, Link 2.
Every month on average we see 1 full moon, the earth goes round the sun once every year, that means 365 days. However each time a full moon appears is about 29 or 30 days, which means in 12 months that is only on average 29.5 x 12 = 354 days, which means in a year, there is an extra 10 to 11 days. In about 3 years, there will be an extra 30 ish number of days. So u will see an extra full moon after each three years, on that 3rd year, u will have 13 full moons. That extra moon is given the name Blue Moon. Interesting right?
Hereby, i wish to take this opportunity to greet all my friends Happy New Year!
