Suhoor and iftar
In Ramadan, the fast begins at Fajr and ends at Maghrib. Many communities also publish Imsak, a few minutes before Fajr, as a caution for stopping suhoor.
On Salah Times, Imsak is ten minutes before calculated Fajr. That is a planning convention, not a fatwa. If your mosque prints a different Imsak, use the mosque.
Open your city page for today’s Imsak and Maghrib. The monthly table is useful for planning a travel month; still check the congregation time locally.
