Download the complete collection in ZIP format including all 'MovingOperation' files.

Sometimes an Internet-link is mentioned on the last line(s) of the file.

Don't forget that there is a possibility to import one or a few data-lines of a chapter into the 'organizer' (if only a few lines are interesting for you).
Open the 'Organizer' window, click the button 'Holiday', the 'Special Days' window opens.
There you can OR make an entire chapter active OR import one line at a time into the 'organizer' ('Click a date to insert it into the organizer').
The second solution gives also the possibility to add a specific image (different from the image that goes with the chapter).
If you do so, don't forget to fill in the other fields ('Time', 'Repetition', ...).
This is even the only way to add data coupled to the Easter date in the 'organizer'.

Take attention for one point: if the chapter needs a 'Moving Operation' formula (always mentioned in the beginning of the chapter, you need to copy the 'MovingOperation_###' formula to your 'Holidays' directory.
The 'MovingOperation' files are in the same directory, and are included in the ZIP-file.


The ‘Images’ mentioned in the different chapters are not all the basic ‘Images’.
This link gives access to the ‘Images’ page with all ‘Images’ used in the mentioned chapters.
You can copy the images you want to use to your images directory on your PC (subdirectory from PTBSync)

[Usually C:\Program Files\PTBSync\Images (Windows XP)]

Link to the 'Images'

Some are original (if so, they have the same name as the original ‘Image’).
Some are adapted.
Some are made by me.

Images beginning with 'aan-...' are animated (moving) images.
They begin with ‘aan-..’ to group them and to separate them from the non-moving ‘Images’.
‘aan-zzz.gif’ is a separator file to separate the moving and non-moving ‘Images’ in the directory.
(above the separator the moving images, under the separator the non-moving images).


You can contact me in English or Dutch on my e-mail: dewaelheyns(a) with suggestions, remarks, corrections, …

Basic information

If you are curious about (some of) the information used to make the chapters, you can look in the mentioned Directory.
BUT this is basic information, it can be in different languages, and there is no special layout.

An example for the calendars: Word document about Era's
