Can you fast when you're not in Ramadan? and Do you get reward if you fast the day before Eid?

Can you fast when it's not Ramadan? and do you get reward if you fast the day before eid. And do you get reward if you fast when it's not Ramadan?

Dear Brother / Sister,

It is permitted to fast outside Ramadan, too. It is very meritorious to fast on the Eve of Eid al-Adha. Surely, the fasts other than Ramadan days are meritorious.
Our Prophet (PBUH) says: “I hope that Allah forgives the sins of the second and following years of the one who fasts on the Eve of Eid al-Adha. However, it is not recommended for the pilgrims standing for prayer on the Arafat Hill on the Eve Day. However,  it is recommended for Muslims except pilgrims to fast on that day." (Muslim, Siyam:1162)
