All Russian Saints

In the Russian Orthodox Church, the second Sunday after the Feast of Pentecost is traditionally the day when all the saints of the Russian land are commemorated. In a way, this service (and others that follow the same pattern) are an extension of the service of the first Sunday after Pentecost, which is kept as the Feast of All Saints (not to be confused with All Saints' Day in the western Churches, which is celebrated on November 1).
