Feast Day:  40 days after Pascha (Revised Julian Calendar, aka New Calendar)

Troparion — Tone 4

O Christ God, You have ascended in Glory, / granting joy to Your disciples by the promise of the Holy Spirit. / Through the blessing they were assured / that You are the Son of God, / the Redeemer of the world!

Kontakion — Tone 6

When You had fulfilled the dispensation for our sake, / and united earth to heaven: / You ascended in glory, O Christ our God, / not being parted from those who love You, / but remaining with them and crying: / “I am with you and no one will be against you!”
