This web site and these programs were developed, managed,
and maintained by Laszlo Kiss, as his own work, until his death in 2011.
It is now maintained by the Divinum Officium Project
(email canon DOT missae AT gmail DOT com).
It represents no official order,
nor the view or opinion of any group. Laszlo wrote: I tried to follow my sources,
but naturally the more I work on this project the more mistakes I make.
Such a project can be done only by teamwork. I keep doing this in the hope
that a team will pick up the idea, and will use the computers in their entirety
to worship God. Since August 2011, the Divinum Officium Project
continues Laszlo Kiss's work and keeps his hope alive.
Words of caution:
Those who are obliged to recite the office should do so from canonically
approved books. (Can 276.2.3) According to the motu proprio Summorum Pontificium Cura of Pope Benedict XVI (7 July 2007),
only the 1962 books are accepted as the Extraordinary Form of the Roman Rite.
The Project makes every effort to maintain in this website the Rubrics 1960
version to be identical with the 1962 typical edition. The website is seeking ecclesiastical approbation as such.
- The Project consults written sources for the Divino Afflatu and Trident 1910
and Trident 1570 and Reduced 1955 versions and follows them carefully, as much as possible.
- The pre Trident monastic version is a projection backward in time.
- The 1960 Newcalendar version is a hypothetical projection forward devised by Laszlo Kiss,
and probably disapproved by the Ecclesia Dei Commission's January 20, 2010 (Prot. 13/2007)
decision as an accepted form of the Liturgy.
Historical versions of the Divinum Officium
The Divinum Officium was the official prayer of the Roman Catholic Church for
at least 1500 years, until 1971, when it was significantly changed to
The Liturgy of the Hours. This programlet, as conceived by Laszlo Kiss,
is partially a device enabling one to pray the Office easily,
and partially a historical document to
visually show the changes in the last few hundred years. These purposes are
maintained by the Divinum Officium Project since August 2011, with the intent
that the software and website should be usable and historically accurate.
This project shows how the daily Office was collected from the same psalms, lections, hymns,
versicles and responsories for the different versions:
- The pre-Tridentine Monastic version is an attempt to illustrate the
Benedictine Breviary, as it is described in the
Regula of St Benedict, with the exception that for lack of resources only 9 lessons
are included for Sundays and Feasts instead of 12 lessons.
See details below
- The version ordered after the Council of Trent by Pope St. Pius V,
which, except for the ever increasing number of feasts in the Proprium Sanctorum, was virtually
unchanged until the 20th Century. This Tridentine version was based essentially on the Roman Rite in use at this time.
Therefore, the majority of psalms were prayed in Matins, Lauds, and Vespers. The little hours contained the same Psalm 118 everyday, which was memorized
by heart and could be prayed without a book, at the little hours. Sunday Matins contained
18 psalms, and the weekday Matins contained 12 psalms. Lauds and Vespers were considerably
longer, due to the length of of the psalm and their suffragia. The Feasts of Saints offered
some relief in the number of psalms. Those Matins consisted of 9 psalms only, which broke the
rule of the required 150 psalms a week. The number of Festive Offices came to exceed
the number of ferial Sunday Offices, when more than two thirds of the days were Festive
The Trident 1570 version uses the original
1570 calendar, the Trident 1910 version uses the permanent calendar from the
1888 Pustet edition Hiemalis volume. The two differ only in the calendars.
Both use the Clementine psalter, as well as the same rubrics. We are seeking to add the pre-Urban VIII hymnody for the Monastic and 1570 hours, and as an option for the other forms. Please help.
See details below.
- The Divino Afflatu version is named from the
Encyclical of St. Pius X., and was the Official version from 1911 to 1960. St Pius X mixed
- The version uses the ferial psalms for the festive offices except for the
1st and 2nd class feasts, and for a few others which antiphons hand down for a feast.
The Tridentine version Seasonal mode is an attempt to show the effect of this change
without the change of the Psalter
- Also, psalms are divided into a weekly cycle without significant repetition
of the psalms (9 psalms for Matins, 5 each for the major hours, 3 each for the minor
hours). The encyclical also shortened significantly the suffragia, and other parts of the office,
reducing the time at prayer about 20%.
The Divino Afflatu version uses the permanent Kalendar from the printed 1943 Pustet
edition, Hiemalis volume.
Missing offices are updated as sources allow.
- The version Reduced 1955 is based on
Cum Nostra Hac aetate decree, and the version
Rubrics 1960 ordered by the Motu Proprio
Rubricarum Instructum 1960
of John XXIII. These changes further shortened the prayer time by an additional 5% and 15% respectively.
Both versions use the permanent calendar from David Siefker's
Missing offices are updated as sources allows.
See details below
The 1960 New Calendar version implements the
2009 Ordinary Form calendar. It uses the 1960 rubrics, which is now the
Extraordinary Form of the office. It is merely an experiment, on the idea that this form should
be the living prayer of the Church.
See details below
Laszlo prayed the Divino Afflatu version personally, but the main point of this project
was and is to show that the changes published in 1955 and 1960 are not more than the changes
which were made in 1911 by Divino Afflatu. In all changes, the reason was to simplify and shorten

except that in the Tridentine version, Feasts of semiduplex rank and above use the Festive
psalms, which is three nocturns each of three psalms for Matins, with a slightly different set for holy men and holy women, with the Sunday psalms from the

and Lent. In the Tridentine version, each Ferial Office Lauds began with Psalm 50 (Miserere),
and only the 2nd and 4th (canticle) change throughout the week.
The Little Hours have the same psalm set over the week, but the antiphons change according to
the day of week.

- 1st class: unchanged.
- First week of month (from August to November) always starts in the month,
instead of the closest Sunday to Kalendas.
- Some additional Kalendar changes are implemented.
1960 New Calendar version changes:
- implementing the 2009 Calendar ( http://en.wikipedia.org/wiki/Roman_Catholic_calendar_of_saints) Only those offices are parts of the office for Proper of Saints, which are listed here; some offices are relocated. Offices not found in the Extraordinary form, are created from the Common of Saints
- Memorial offices are implemented as 3rd class offices according to the 1960 rubrics (1, 2-3 readings from the season, 3rd reading from the saint). Feasts are implemented as 2nd class (semifestive offices), solemnities as 1st class (festive) offices
- optional memorial offices are prayed in 'regular' mode, the ferial office is used in 'seasonal' mode, except for Advent, when always the ferial office is recited if the saint's office is optional
- in Lent all memorial offices are trumped by the ferial office, in accordance to the 1960 rubrics (there is only Gospel homily, no Scriptural reading for the season)
- if two saints are assigned for the same day, the first in the calendar is chosen
- commemoration of a saint would be implemented only for local Feast or Solemnity in the O antiphon (Dec 17-24) days in Advent
- Seasonal feast days moved to Sundays (Ascencion etc) cannot be handled, there would be no office left for the feria. Feasts days of saints can be moved through the translation table (Latin/Psalterium/Trnewcal.txt, Latin/Psalterium/Trnewcalyyyy.txt)
- Ember days, Rogation days, and the Octave of Pentecost is dropped following the previous trend since 1955; however the lessons are Gospel homilies for that days
- The traditional schema of Sundays (Septuagesima time, 6 Sundays after Epiphany and 24 Sundays after Pentecost) is not changed because any change of this would require to create a new scriptural reading schema

Dominicales and the Suffrages are included for duplex offices in case of Tridentine or
Divinu Afflatu versions.
For Tridentine versions seasonal mode also uses the ferial psalter for
duplex or lesser offices
