Dónde y donde
Por qué la palabra dónde as veces tiene un tilde y as veces non?

To add to what jellonz said, "dónde" or "adónde" can be interrogative even if they are not inside a question. for instance "me pregunto dónde estarán las llaves". If that "dónde" is unknown, it will have an accent mark.
I've learnt "dónde" when it's an interrogative, otherwise "donde", but I have seen many cases where this rule is rightly or wrongly ignored.
¿Dónde está la ciudad donde vives? - Where is the city where you live?
And don't forget "adonde" (or "a donde") when the "where" could translate as "to where" in English.
¿Adónde vas? - [To] Where are you going?
Adonde vas es importante - [To] Where you are going is important.
Again, I've learnt tilde for interrogative, no tilde otherwise, but again I've seen this not adhered to. Maybe misuse? Maybe regional? Maybe a change in the RAE's requirements? Maybe I learnt wrong?
This question was discussed before with explanations. About donde and dónde
