Have you encountered a parish record where the date of a baptism, marriage or burial is expressed according to a liturgical calendar, such as the third Sunday after Trinity or the first Sunday after Pentecost? These dates can be intimidating but are decipherable into standard dates if you know where to look.
First, let’s define the liturgical calendar, which for Christian churches follows the life of Christ. The liturgical year begins with Advent (waiting for the birth of Christ) four Sundays before Christmas. The church Christmas lasts 12 days* from Christmas Day (fixed date) to Epiphany on January 6.
The interval before Epiphany and the beginning of Lent on Ash Wednesday is “ordinary”, i.e., ordinal or “counted time.” Lent, which begins on Ash Wednesday and lasts forty days (not counting Sundays). Easter (the Resurrection) falls on the first Sunday after the first full moon after the first day of Spring. Pentecost, (the ascension of Christ), also known as Whitsunday, is celebrated 50 days after Easter. The Sundays after Pentecost and before the start of Advent are counted as “after Trinity.”
In addition to a basic understanding of the liturgical year, it’s also important find a reliable calendar based the following factors for your ancestors:
1. Denomination (Lutheran, Catholic, Methodist, etc.)
2. Country; and
3. Julian or Gregorian Calendar.
