Muslim Space follows the Fiqh Council of North America in determining dates of the Islamic calendar. They have issued the following information with regards to Ramadan 1443/2022.

Ramadan 1443 AH:
The Astronomical New Moon is on Friday, April 1, 2022 at 6:24 Universal Time. On that day, everywhere in North and South America at sunset the elongation is at least 8 degrees and moon is at least 5 degrees above the sun. Therefore, first day of Ramadan 1443 is on Saturday, April 2, 2022, insha'Allah. Tarawih prayer will start on Friday night.

Eidul-Fitr 1443 AH:
The Astronomical New Moon is on Saturday, April 30, 2022 at 20:28 UT. 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 1443 cannot start the next day. Hence first day of Shawwal is on Monday, May 2, 2022, insha'Allah.
