Dragon breath weapons used to be simple: 3 uses per day. They magically recharged at either midnight or dawn, depending on your DM.

As I read through the dragon section, I see new (to me) info on Lair and Legendary actions, environmental effects, and more. Those all seem pretty straight forward. However, when I get to the actual stat blocks for dragons (for a Black Dragon), I see stuff like:

Acid Breath (Recharge 5–6).

Did I miss where this was explained? What exactly does this 5-6 mean?

How/when does an ability like a dragon's breath weapon recharge, if it's listed as "Recharge 5–6"?

This is explained under "Limited Usage" on page 11 of the Monster Manual or here in the basic rules on D&D Beyond:

Recharge X–Y. [...] At the start of each of the monster's turns, roll a d6. If the roll is one of the numbers in the recharge notation, the monster regains the use of the special ability. The ability also recharges when the monster finishes a short or long rest. [...]
