What Fat Tuesday 2017 Meant and How the Date Is Determined
Fat Tuesday 2017 occurred on February 28, 2017, the day before Ash Wednesday and the start of Lent in the Christian calendar. Also known as Mardi Gras or Shrove Tuesday, this moveable feast is scheduled as the day before the beginning of Lent, which always starts on Ash Wednesday and is calculated from Easter Sunday. Because Easter follows a computus based on the first Sunday after the first full moon on or after the March equinox, the exact civil date of Fat Tuesday changes each year. In 2017, this placed the celebration on February 28.
Mardi Gras and Lent: Core Concepts Behind Fat Tuesday
Mardi Gras as a Moveable Feast
Mardi Gras, French for "Fat Tuesday," marks the final day of festivities before the penitential season of Lent. It is not a fixed date but is tied to Easter through ecclesiastical rules. The name references the practice of using up rich foods such as eggs, milk, sugar, and meat before the fasting period begins. The timing of Easter determines both the date of Ash Wednesday and, consequently, the date of Fat Tuesday in any given year.
Ash Wednesday and Lent
Ash Wednesday signals the beginning of Lent, a roughly six-week period of reflection, fasting, and preparation in many Christian traditions. By calculating Lent from Easter, the church ensures that this season of repentance mirrors the 40 days Jesus spent in the wilderness. Because Fat Tuesday immediately precedes Ash Wednesday, its date fluctuates in sync with Easter, producing years like 2017 where it fell on February 28.
How the Date for Fat Tuesday Is Computed
The date for Fat Tuesday depends on the date of Easter, which is set by rules established at the Council of Nicaea in 325 AD and refined in the Gregorian calendar. Once the Easter date for a given year is known, the liturgical calendar can be fixed:
- Easter Sunday is the first Sunday after the first full moon on or after the March equinox.
- Ash Wednesday is 46 days before Easter Sunday (40 fasting days plus six Sundays that are not counted as fast days).
- Fat Tuesday (Shrove Tuesday) is the day before Ash Wednesday, placing it exactly 47 days before Easter Sunday.
In 2017, Easter Sunday was April 16, so Ash Wednesday fell on February 1 and Fat Tuesday was February 28.
Global Traditions and Cultural Impact on Fat Tuesday 2017
New Orleans and the United States
In the United States, Fat Tuesday is strongly associated with New Orleans, where Mardi Gras parades and balls mark the season. In 2017, many organizations scheduled parades and events around the February 28 date, including krewe processions that have become a staple of local culture. Because the holiday is tied to Easter, the timing relative to school terms and work schedules can shift noticeably from year to year.
Carnival Celebrations Around the World
Globally, the period leading up to Fat Tuesday is often called Carnival, with street parties, costumes, and public festivities. In Brazil, the Samba schools prepare for their parades in the Sambadrome; in Venice, elaborate masks and historical pageants draw international visitors; and in many European countries, rich foods are consumed before the fasting period. Each region adapts the timing to the same liturgical calculation based on Easter, which means the civil dates of these events move forward by up to a month from year to year.
