The
Ordo Romanus fixed the spring fast in the first week of March (then the first month), thus loosely associated with the first Sunday in Lent; the summer fast in the second week of June, after
Whitsunday; the autumnal fast in the third week of September following the
Exaltation of the Cross, September 14; and the winter fast in the complete week next before Christmas Eve, following
St. Lucy's Day (Dec. 13). These dates are given in the following Latin
mnemonic: Or in an old English rhyme: "Lenty, Penty, Crucy, Lucy" is a shorter mnemonic for when they fall. The ember days began on the Wednesday immediately following those days. This meant, for instance, that if September 14 were a Tuesday, the ember days would occur on September 15, 17, and 18. As a result, the ember days in September could fall after either the second or third Sunday in September. This was always the liturgical Third Week of September, since the First Sunday of September was the Sunday closest to September 1 (August 29 to September 4). As a simplification of the liturgical calendar,
Pope John XXIII modified this so that the Third Sunday was the third Sunday actually within the calendar month. Thus if September 14 were a Sunday, September 24, 26 and 27 would be ember days, the latest dates possible. With September 14 as a Saturday, the ember days would occur on September 18, 20 and 21, the earliest possible dates. Other regulations prevailed in different countries, until the inconveniences arising from the want of uniformity led to the rule now observed being laid down under
Pope Urban II as the law of the church, at the
Council of Piacenza and the
Council of Clermont, 1095. Prior to the reforms instituted after the
Second Vatican Council, the
Roman Catholic Church mandated
fasting and
abstinence on all Ember Days, and the faithful were encouraged (though not required) to receive the
sacrament of
penance whenever possible. On February 17, 1966,
Pope Paul VI's decree
Paenitemini excluded the Ember Days as days of fast and abstinence for Roman Catholics. The revision of the liturgical calendar in 1969 laid down the following rules for Ember Days and
Rogation days: They may appear in some calendars as "days of prayer for peace". The
Evangelical Lutheran church calendars continue the observation of Ember and Rogation days. The Ember Days are observed through "fasting, prayer, and almsgiving". The Ember Days are used by Evangelical Lutheran priests to instruct the faithful in the
catechisms. so that if September 14 is a Sunday, Monday, or Tuesday, the Ember Days fall on the following Wednesday, Friday, and Saturday (in the second week of September) whereas they fall a week later (in the third week of September) for the Roman Catholic Church (except in the
Ordinariates for former Anglicans, which also follow the traditional dating for Ember Days). ==Ireland==
