The short answer to this question is: The rendering of the main (mapnik) map should typically update within a few (tens of) minutes, however occasionally it can take longer. The longer answer is a little more complicated, as there are many components that interact in subtle ways to produce the updated results. So I'll try and explain the process, which may be a little technical at points: First of all, if you edit OpenStreetMap data, your changes get applied to the main database and are immediately visible from the API. The rendering of the map however uses a secondary database that needs to be kept updated from the main database.

For this purpose, the main database publishes minutely diffs that are then applied to the rendering database on OpenStreetMap.org and other rendering servers. Once the new data is in the rendering database, it then needs to actually get rendered. In most cases hitting the refresh button a couple of times a few minutes apart will fix these issues. Why haven't my changes appeared on the map? There are kind of two parts to the answer to your question. For one, the data you add to the database is used in many different applications. For example for rendering map tiles, for using on your phone, for routing, in your Garmin devices, for your satnav, for searching, to make art work, in flight simulators and many more applications. Each of these applications have their own separate update schedule. For some applications it might only take minutes for the update to trickle through, other applications might only update every month or so.

However, due to this huge diversity of uses of the data, your data will be immediately useful for some. The other part of your question is how often does the "mapnik" map view on openstreetmap.org update. The Internet Movie Database (IMDb) Wikipedia. Wikibooks. Commons. Wikiquote. Wikispecies.
