Does the Muslim prayer time change every day?
Yes, slightly. About a minute a day. Going up in the A.M. and down in the P.M. See the site I link to below.
Note that the last Sunday of October starts daylight savings time so the times start to offset back one hour on the 27th. ALSO NOTE, that one of the earlier shootings occurred right at one of the evening prayer times. BUT afternoon and evening prayers can be COMBINED. This is permitted. Especially if the Muslim is "traveling".
