Over 61,000 indentured labourers were shipped from India to work Fiji's sugar plantations under the harsh five-year "girmit" contracts, most from the Awadh and Bhojpur regions of northern India. The majority who stayed were Hindu, but a substantial minority — historically around a sixth of Indo-Fijians — were Muslim, and their descendants built the mosques that now anchor communities across the old sugar belt: Nadi, Ba and Lautoka on Viti Levu's western side, alongside Suva and the northern town of Labasa.
Fiji's geography adds an unusual twist: the archipelago straddles the 180th meridian, and the International Date Line was drawn to bend around the country's eastern islands so all of Fiji shares a single date and time despite lying on both sides of the line in theory. Because the inhabited islands are relatively compact and close together, though, prayer times calculated for Suva stay reasonably close to those in Nadi or Labasa, unlike sprawling mainland countries where a capital's schedule tells you little about the rest of the nation.
Sitting at around 18° south of the equator, Fiji has fairly stable day lengths year-round, making the Muslim World League's standard Fajr and Isha angles — the convention most Fiji Muslim League mosques already lean on in the absence of one binding local method — a dependable choice.
The International Date Line bulges eastward around Fiji specifically so the whole country — including its easternmost islands — shares one calendar date, avoiding the confusion of a nation split between today and tomorrow.
Not by much — Nadi sits only around 0.6° of longitude west of Suva, so Maghrib and Fajr times typically differ by just a couple of minutes between Fiji's two largest Muslim population centres.
Only modestly — Fiji's tropical latitude means daylight hours swing by roughly two hours between the December and June solstices, a far gentler seasonal shift than higher-latitude countries experience.
The great majority are Sunni, with a smaller Ahmadiyya presence; there is no significant historical Shia community, reflecting the regional origins of the original indentured migrants.
