Learn Spanish (Spain): ¿A qué hora quedamos?

In Spanish, the present tense is often used to make suggestions or talk about immediate future plans. Asking ¿...quedamos? is the most natural way to say "shall we meet?" or "what time are we meeting?".

I thought quedar meant "to stay". Why does it mean "to meet" here?

Quedar is a very common verb in Spain with multiple meanings. When used on its own like this, it means "to arrange to meet" or "to meet up". If you want to say "to stay" (like staying at home), you must use the reflexive form quedarse.

Why is there an A at the very beginning of the sentence?

In Spanish, when you ask at what time an event happens, you must include the preposition a. While in English we often just ask "What time...?", Spanish requires ¿A qué hora...?.

Could I use encontramos or conocemos instead of quedamos?

Not for this situation. Conocer means to meet someone for the first time. Encontrar usually means to find or bump into someone by accident. When you are making plans to hang out, quedar is the exact verb you need.
