JDMonthName
Here is a small piece of code to obtain the string data for a correctly converted gregorian date:
<?php
$arDateFrench = gregorian2FrenchDateArray(11, 9, 1799) ;
echo $arDateFrench[1] . " " . $arDateFrench[0] . " " . $arDateFrench[2] ;
/* the output will be:
18 Brumaire VIII
*/
function gregorian2FrenchDateArray($m, $d, $y)
{
$julian_date = gregoriantojd($m, $d, $y);
$french = jdtofrench($julian_date);
if($french == "0/0/0")
return "" ;
$arD = split("/", $french) ;
// get the month name
$monthname = FrenchMonthNames($arD[0]) ;
/* convert the year number to roman digits (as most historians do and documents of the time did */
$stryear = decrom($arD[2]) ;
return array($monthname, $arD[1], $stryear ) ;
}
function FrenchMonthNames($mo)
{
/* The names have been invented by Fabre d'Églantine, a second or rather third rank poet
of primarily pastoral poems, with each name referring to the respective period in the agricultural year; e.g. "Vendémiaire" (approx. September) is derived from "vendange" ("harvest"), "Brumaire" (Ocotober/November) from "brume" ("fog") and so on ... */
$arMo = array("Vendémiaire",
"Brumaire",
"Frimaire",
"Nivôse",
"Pluviôse",
"Ventôse",
"Germinal",
"Floréal",
"Prairial",
"Messidor",
"Thermidor",
"Fructidor",
"Sansculottide") ;
if($mo < count($arMo)+1)
return $arMo[$mo-1] ;
}
function decrom($dec){
$digits=array(
1 => "I",

Very limited function:
(extract from source of 4.3.3)
These routines only convert dates in years 1 through 14 (Gregorian dates 22 September 1792 through 22 September 1806). This more than covers the period when the calendar was in use.
Pour les français :
Ces routines ne converitssent les dates que de l'an 1 à 14 (du 22 septembre 1792 au 22 septembre 1806). Cela couvre plus que la période pendant laquelle le calendrier à été utilisé.
