For Subud members interested in fasting during Ramadan 2018, here is the information:
Ramadan 1439 AH:
The Astronomical New Moon is on Tuesday, May 15, 2018, at 11:47 Universal Time. On that day, somewhere in the Pacific Ocean at sunset, the elongation is 8 degrees and moon is 5 degrees above the sun. Therefore the first day of Ramadan 1439 is on Wednesday, May 16, 2018, insha’Allah. First Tarawih prayer will be on Tuesday night.
Eid ul-Fitr 1439 AH:
The Astronomical New Moon is on Wednesday, June 13, 2018, at 19:43 Universal Time. On that day there is no place on earth where at sunset the elongation is 8 degrees and moon is 5 degrees above the sun. Therefore, Shawwal cannot start the next day. Hence, the first day of Shawwal 1439 is on Friday, June 15, 2018, insha’Allah.
This would make the first day of fasting Wednesday, May 16.
