The programlet comes up with the page:

main page

The first line shows the day's Office (or that which is selected), the second line (if any) is the Office which is commemorated, or the Scripture which is read at Matins that day. In the top line, feasts are shown in red; vigils and offices of Our Lady in blue; and that of a feria, simplex or commemoration in black.

In the next line, the widget after the title allows to reset the date. The programlet always comes up with the current date, but you may select a different date by pressing
  • down arrow for the previous day;
  • up arrow for the next day;
  • or by typing in a new date.
After the change you must press the button next to the widget to obtain the new Office.

The images in the main table serve only remind the reader that the Office is collected from the
  • Ordinarium = the frame of the Hours;
  • Psalterium = the Psalms, forming the main portion of the Hour;
  • Proprium de Tempore = the days as they are part of the seasons of the Church year;
  • Proprium Sanctorum = the feasts of the saints;
  • Commune Sanctorum = the common part of the offices for the saints.
You may find further details at the Technical Information or Rubrics pages.

The eight buttons in blue show the eight hours of the traditional Divine Office; you may select one by clicking on the tab. If you recite the hours in sequence (and your browser allows cookies) then the already-completed hours will be listed in the same color as the titles.

Since you have arrived at this page, you have already used the Help button from the bottom. Try clicking the Options button to find the following table:


Check or uncheck the priest box, so you will recite the Dominus vobiscum or the Domine exaudi as appropriate.
If you check the Building script box, the program will make a list at the bottom how the Office for the hour was composed.
Language selects the language for the first column.
You may select white or grey background for the tables of the individual hours.
The structure of the colors input is: -relative size [bold] [italic] foreground color.
If the starting page image extends far beyond the screen, set screen height to a smaller value.

Click OK to get to the main table again. If your computer allows cookies, this values and the ones on the bottom row will be saved for the next session.

The five selectors on the bottom row allows you to control how the Hours are rendered.


The first selector displays the Office in different formats.

To pray the hour, please select any mode other than skeleton:
  • all prints everything, including the common prayers. (Default)
  • psalms only indicates the common prayers.
  • nothing prints only the Ordinarium; the psalms, lections and other longer items are only indicated.
  • skeleton prints only the structure of the Hour.
For instance, click now on the leftmost selector, choosing skeleton and click on the Completorium button.

The programlet shows the skeleton of the easiest-to-compose Hour, that of Compline.


If you select "Psalms", this will result:


  • Click the button next to the indicated element in the Hour, and the text will come up in a separate window as a popup. The picture shows the Pater Noster as popup.

    expanded and popup

  • In any selection, clicking on Top brings the cell to the top, Next brings the next cell to the top.

  • The number in the right cell is for reference.

  • If you click on any radio button next to the section title, that part will be expanded. Click an another to change the expanded part, or on the same section's button again, to contract the expansion.

The second selector chooses the rubrical structure, of which 7 options are provided. The programlet defaults to the 1960 rubrics.

The third selector selects "Regular" or "Seasonal" mode, which in certain cases will allow one to pray the Office of the season as opposed to that of the day. See Versions for details.

The fourth selector designates the language in which the Office is displayed in the right-hand column. If a translation is not fully available in a particular language, the second column in the displayed Office will default to English text. If you select the same language as the first column, only that language will be displayed in a single column.

The fifth selector permits a choice from among several votive Offices, such as the Officium Defunctorum or the Officium Parvum of the Blessed Virgin Mary.

Within the text:
  • ✝︎ stands for the regular Sign of the Cross (forehead, breast, left, then right shoulder).
  • ✠︎ stands for making a cross with your thumb on your lips.
  • + stands for making a cross with your thumb on your breast.

  • You may also change the date by clicking on Kalendar tab. The Kalendar is divided in two columns: the Proprium de Tempore and the Proprium Sanctorum. On a given day, the side which is displayed in bold-face type represents the correct Office for that day in a specific rubrical structure (i.e. Rubrics 1960).

    One can select another date by clicking the day of the month in the first column. Also, you may change the year or month at the top, or the rubrical structure (1570, 1910, etc.) at the bottom of the page.


    If Divinum Officium has been downloaded to one's computer as a local web host (or via GitHub), it is possible to edit the individual files.

    It is our hope that this programlet will help everyone to understand the Divine Office better, and help people to start to pray fully (or at least partially) the Breviarium Romanum on a daily basis.
