GW2 doesn't signpost content/quests, there is no one to speak to to start an event (in most cases anyway!). GW2 is about exploration, there are dynamic events happening all the time, you just go join in if it's something you fancy doing.
In each zone there are also 'Heart Quests' in fixed locations, but these are one time deals, not repeatable like the normal events (well you could redo them, but you don't get anything).
There are also numerous world bosses that appear at set times all over Tyria, see here:

Then you have hidden jumping puzzles to discover, Dungeons when you are high enough level, Fractals when you're lv80, and then all the Living World stuff every couple of weeks on top of that.
