The commemoration of Holy Days, including the development of
programs for these observances, is a matter left to the discretion of the
appropriate National and Local Spiritual Assemblies, which are entrusted with
the responsibility of ensuring that such observances are conducted in a manner
in keeping with the spirit of the divine teachings and ordinances. While it is
customary for the Tablets of Visitation to be recited at the conclusion of the
Holy Day programs held at the Bahá'í World Centre, as well as in countries of
the Middle East, this practice is not binding upon Bahá'í communities
elsewhere, nor has a specific time been fixed for the recitations to occur.
