Leviticus 23:2

Leviticus 23:2 Speak to the children of Israel, and say to them, As to the appointed feasts of Jehovah, which you shall proclaim as holy convocations, these are My appointed feasts.

A convocation is a special assembly called for a special and particular purpose. The feasts appointed by Jehovah as holy convocations signify the gathering of God's redeemed people to have a festival with God for His joy and enjoyment that the redeemed may participate in it with Him and with one another. A festival, therefore, was for nothing except rest and enjoyment. This rest and enjoyment were not individual but corporate.
