6 days of Shawwal

The month of Shawwal comes after the month of Ramadan and it is recommended to fast in the months Shawwal for six days after Eid-ul-Fitr.

It is recommended to fast the first 9 days of Zul- Al-Hijjah, but Day of Arafah which is 9th Zul Al-Hijjah is highly recommended.
 Abu Qatadah reported: The Messenger of Allah, peace be upon him, was asked about the observance of fasting on the day of Arafah. He said, "It is an expiation for the sins of the preceding year and the current year" [Muslim]

Days that Prophet Muhammad PBUH forbade us to fast are:

• Two days of Eid  
• Fasting the 11, 12, 13th of Zul- Al-Hijjah 
• Fasting during menstruation or childbirth in women. 
• Fasting when you are sick and it may harm you.  

Fasting itself is a form of worship and the sunnah fasting is not obligatory which makes the voluntary fasting like extra credit for us, so use the extra credit opportunities to get closer to Allah.
