Trinity Parent Saturday in 2025 falls on June 7th, preceding Trinity Sunday on June 8th. As one of the main memorial days of the year, it is a time to commemorate deceased loved ones and all departed souls. This day has specific customs and rules that are traditionally observed by Orthodox Christians.

The day is marked by church services, including liturgies and requiems. Believers often bring lenten foods, fruits, sweets, and liturgical wine to the church to be sanctified and shared. Notes with the names of deceased relatives can be given to the priest for prayer during the service, and a Forty-day Liturgy can be requested for continued commemoration.

After the church service, it is customary to visit cemeteries to tidy up graves of relatives and friends, and even to care for neglected graves. In the evening, families gather for a modest memorial dinner with lenten dishes, including kutia, a whole-grain porridge with honey, raisins, and dried fruits. The table should not be lavish, and delicacies should be reserved for other days.

Certain activities are discouraged on Trinity Saturday. It is not recommended to host extravagant celebrations, quarrel, or excessively grieve the deceased. The day should not be combined with personal holidays like birthdays or weddings.

Several weather-related signs are associated with Trinity Saturday. Rain on this day is believed to signify abundance, while a rainbow after the rain indicates good luck and well-being. Heat suggests a dry summer, and dew may foreshadow early frosts. Some believe that dreams of deceased relatives on the preceding night may offer wise counsel. Bringing an aspen branch into the house is another tradition, with its rate of drying believed to indicate the nature of the coming year.
