Unlike countries where one immigrant group defines the local Muslim community, Italy's is genuinely mixed: Moroccans, Albanians, Bangladeshis, Egyptians and Pakistanis each make up meaningful shares, with the heaviest concentrations in Lombardy and Emilia-Romagna rather than in Rome itself. Rome's own Grand Mosque, the Moschea di Roma, opened in 1995 and was for years one of the largest mosques in Western Europe, serving a capital where Muslim residents remain a much smaller share of the population than in Milan or Turin.
Italy also carries a far older, indirect Islamic imprint: Sicily spent roughly two centuries under Arab-Muslim rule as the Emirate of Sicily before the Normans took the island in the 11th century, leaving traces in Sicilian architecture, agriculture and vocabulary that predate any of today's immigrant communities by nearly a thousand years. That history has no bearing on how modern prayer times are calculated, but it explains why Islam in Italy is not simply a 20th-century arrival.
Italy has no single Islamic authority equivalent to a national fatwa council, so mosques from Rome to Milan generally default to the Muslim World League's 18°/17° angles for Fajr and Isha — a globally recognized standard that works reasonably well at Italy's mid-latitude and avoids picking a side among the country's many distinct immigrant communities.
No — the times on this page are calculated directly from Rome's coordinates using the Muslim World League method, independent of any single mosque's own posted schedule, though the Grand Mosque's timings should be very close.
Milan sits about 3.5° further north and slightly further west, so its sunrise, sunset and the resulting Fajr and Isha times shift by several minutes compared to Rome on the same date, especially in summer and winter.
The underlying solar calculation doesn't change, but Italy's clocks move forward an hour each spring and back each autumn (CET to CEST and back), which shifts every prayer's displayed clock time by an hour on the changeover date.
No original mosques from the Emirate of Sicily period survive intact — most were converted into churches after the Norman conquest — so today's functioning mosques in Italy are all modern buildings serving the current immigrant community.
