Learn Spanish (Spain): La panadería abre a las siete.

When talking about time in Spanish, you always need a feminine article before the number. This is because it refers to the hidden word horas (hours), which is feminine. Since seven is more than one hour, we use the plural las.

Why is it just abre? Don't I need to say se abre?

You will sometimes see se abre (it opens itself) for things like doors or windows, but when talking about a business's operating hours, Spanish usually just uses the normal, active verb abrir (to open). So, La panadería abre is the standard way to say it.

I recognize pan (bread) inside panadería. Is -ería a common ending?

Yes! Adding -ería to the end of a word is the standard way to name a shop based on what it sells in Spain. For example, carne (meat) gives us carnicería (butcher shop), and fruta (fruit) gives us frutería (fruit shop).

How would I specify "in the morning" in this sentence?

When you attach a time of day to a specific hour, you use the preposition de. You would say a las siete de la mañana. (As a quick reminder, if you were just saying "in the morning" generally, without a specific time, you would use por la mañana).
