The
ember days in Advent--liturgical
Winter--for
2019 are
Wednesday, Friday, Saturday of
this week:
December 18, 20, 21. Roman Catholics are traditionally obligated to
fast & abstain on each of those 3 days, altho' only
partial abstinence is obligated on the Wednesday and Saturday.
[#]Well-catechized Catholic adults equipped with a simple
calendar in 2019 should need no formal announcement, because it'll show them the
fixed date that determines the
movable dates for the Winter ember days. That's December 13, always the Feast of
St. Lucy (
i.q. Lucia), which fell on Friday of last week.
