Azan 247
The azan never stops
Somewhere on Earth, the azan is always being called. As the planet turns, five waves of the call to prayer sweep west around the globe, day and night, without a pause.
Azan 247 shows those waves live on a world map, lets you learn how they travel with a short daily game, and tells you when the next wave reaches you.
The calls are shown as light on a map, never played as sound.

How the map is made
Prayer times are calculated for every square of the map (a quarter of a degree, about 25 km) with the method usually followed in that country; a real mosque may call a few minutes earlier or later.
Each azan is shown for 3 minutes from the calculated time (4 minutes for Fajr).
The number of mosques and musallahs (prayer rooms) in each square is a rough estimate: the ones mapped in OpenStreetMap and Overture Maps, completed where the map is thin from the population (GHSL) and its Muslim share (Pew Research Center).
Where a country has an official mosque total, the estimate was adjusted to match it.
So the numbers are approximate, never exact, and some places with mosques or musallahs may not light up.
Zoomed in, the map shows borders and country names, then cities, towns and villages, and closest each mosque or musallah mapped in OpenStreetMap or Overture at its own place; the other mosques of a place are an estimate, shown at its centre.
The background is satellite imagery: NASA’s Blue Marble on the day side and Black Marble (the city lights) on the night side, meeting along the twilight line. Zoomed in around places with mosques, sharper Copernicus Sentinel-2 imagery (EOxCloudless 2016 by EOX) takes over, darkened on the night side.
