The central question concerns the date of a significant Christian holiday in a specific year. Determining this date requires understanding the method used to calculate its occurrence. The celebrations timing is not fixed on the Gregorian calendar.
Accurately establishing the date requires knowledge of the lunisolar calendar. This is because the calculation relies on both solar and lunar cycles. Historically, this holiday’s date has varied, leading to a need for established rules to ensure consistent observance across different denominations.
