In the Russian Orthodox tradition, Macarius of Unzha's Miracle of the Moose is said to have occurred during the Apostles' Fast and the Feast of Saints Peter and Paul that followed it.

[5] Although the Canadian Doukhobors, a Spiritual Christian denomination, do not venerate saints, the Feast of St. Peter and St. Paul has traditionally been a day of celebration for them.

Since 1895, it has acquired a new significance as a commemoration of the "Burning of the Arms", the Doukhobors' destruction of their weapons, as a symbol of their refusal to participate in government-sponsored killing.

[10] In England, Scotland and Wales the feast is observed as a holy day of obligation while in the United States and Canada, it is not.

[13] Because of the importance of Sts Peter and Paul to the Catholic Church, many Catholic-majority countries observe their feast day as a public holiday.

[citation needed] In Ormoc, festivals, bazaars, parades, and pageants are held annually on the feast day, as Peter and Paul are the city's patron saints.
