Both the Singapore and Indonesia governments have announced that Hari Raya Idul Fitri falls on Tuesday, 24 October 2006, this year.
In Singapore, the Singapore's Mufti has announced that based on hisab estimation, the crescent moon cannot be sighted after today's sunset because it's just 1 minute over the horizon. Therefore, tomorrow (Monday, 23rd of October 2006) will be the completion (30th day) of the Ramadhan fasting month, and that the Hari Raya will fall on Tuesday, 24th of October 2006.
The Indonesian government also announced today that Hari Raya Idul Fitri will fall on Tuesday, 24th of October 2006 because the results of rukyat in 29 places in Indonesia show that the hilal (crescent moon) cannot be sighted during sunset at those 29 places, with hilal of between zero degree and 30 minutes below horizon and one degree over the horizon.
The results are different from Muhammadiyah's announcement, which has decided that the Hari Raya will fall on Monday, 23rd of October 2006 based on its hisab estimation. In this case, the government of Indonesia expressed hope that such differences will not cause any frictions among Muslims in Indonesia.
Meanwhile, the government of Saudi Arabia has announced that the Hari Raya Idul Fitri will fall on Monday, 23rd of October 2006, not because they also have sighted the hilal, but because they have started their Ramadhan fasting month one day earlier, based on the crescent moon sighting result for the start of the Ramadhan month. So today (22nd of October 2006) would be their 30th day of fasting month, and since there's no such thing as fasting for 31 days, they will celebrate their Eid ul-Fitr tomorrow.
Again, I would like to wish all Muslims all over the world, a Happy Eid ul-Fitr celebration. Eid mubarak, Selamat Hari Raya Idul Fitri, mohon maaf lahir dan batin.
