37k seems pretty bloated for something so small?

Good find. It would be nice if it had a list of compatible browsers (aka IE6).

Arold, datepickers take a lot of code in order to make them flexible. Even jQuery UI’s datepicker comes in at 45KB, and thats not even with the required core js or stylesheet. Personally, I think the developer of this calendar did a good job.

“K”, looks better than almost any other datepicker out there that you can download. It looks simple, yet clean and efficient to me.

Thanks for posting about it and thanks for the comments so far

Done !
To limit date from futur just add this code on jsDatePick.full.1.3.js

(line 220) add
this.oConfiguration.limitToFutur = (aConf["limitToFutur"] != null) ? aConf["limitToFutur"] : false;

(line 676) add
if (this.oConfiguration.limitToFutur){
if ( this.isAvailable(this.currentYear, this.currentMonth, parseInt(oDay.getDate()+1)) ){
disabledDayFlag = true;
aDayDiv.setAttribute(”isJsDatePickDisabled”,1);
}
}
