Our masjid timetables are long overdue a makeover, especially with regards to subh-sadiq. Many of us this summer have been using the academic consensus of an astronomical dawn of 18° degrees for subh-sadiq to pray fajr at about 1am, so lets not fall back to mish-mash times when it comes to beginning our fasts in Ramadhan.
Attached is a no-spin Ramadhan 2009 timetable for Newham, London. That means: 1) no minutes have been added to subh-sadiq (dawn), sunrise, and sunset times; and 2) subh-sadiq is calculated according to astronomical dawn of 18° (the time at which the sun starts lightening the sky according to the consensus of astronomers). Esha has been calculated at astronomical dusk minus 3°.
Start your fast a few minutes before the subh-sadiq time listed here end your fast at the end fast time listed here. End fast times are four minutes after sunset because atmospheric refraction means that sunset (and sunrise) times cannot be calculated exactly.
InshaAllah first taraweeh will likely be on Friday night 21st August, the first day of fasting will be Saturday 22nd August, and Eid will be on Sunday 20th September.
