Many Orthodox Christians, including those living in Russia and Ukraine, celebrate Christmas on Jan. 6-7.

Putin, wearing a blue jacket and a high-necked white sweater, crossed himself several times before television coverage cut away to a public service in Moscow's Christ the Saviour Cathedral.

Putin, who celebrated Easter last year in the Moscow's Cathedral with thousands of others, also attended Christmas by himself last year in his official Novo-Ogaryovo residence outside Moscow. In 2021, he attended a public Divine Liturgy in Novgorod.
