"Julian Days are a way of reckoning the current date by a simple count of the"
" number of days that have passed since some remote, arbitrary date. This "
"number of days is called the <firstterm>Julian Day</firstterm>, abbreviated "
"as <abbrev>JD</abbrev>. The starting point, <abbrev>JD=0</abbrev>, is "
"January 1, 4713 BC (or -4712 January 1, since there was no year '0'). Julian"
" Days are very useful because they make it easy to determine the number of "
"days between two events by simply subtracting their Julian Day numbers. Such"
" a calculation is difficult for the standard (Gregorian) calendar, because "
"days are grouped into months, which contain a variable number of days, and "
"there is the added complication of <link linkend=\"ai-leapyear\">Leap "
"Years</link>."

"Les jours juliens sont un moyen de trouver la date courante en comptant le "

" nombre de jours s'appelle le <firstterm>jour julien</firstterm>, "
"abréviation <abbrev>JJ</abbrev>. Le point de départ, <abbrev>JJ=0</abbrev>, "
"est le 1<superscript>er</superscript> janvier 4713 avant J.-C. (ou "
"1<superscript>er</superscript> janvier -4712, puisqu'il n'y a pas d'an 0). "
"Les jours juliens sont très utiles parce qu'ils permettent de déterminer "
"facilement le nombre de jours entre deux évènements simplement en "
"soustrayant les deux jours juliens. Un tel calcul est plus difficile avec le"
" calendrier standard (grégorien) puisque les jours sont groupés en mois, qui"
" contiennent un nombre variable de jours sans compter les difficultés "
"additionnelles liées aux <link linkend=\"ai-leapyear\">années "
"bissextiles</link>."
