aha. OK. Try this but backup your wiki first, this is untested:
/*\
THIS IS A MODIFIED COPY
title: $:/stobot/macros/dateadd.js
type: application/javascript
module-type: macro
Takes a base date and adds days, months or years
\*/
(function(){
/*jslint node: true, browser: true */
/*global $tw: false */
"use strict";
/*
Information about this macro
*/
exports.name = "dateadd";
exports.params = [
{name: "basedate"},
{name: "days"},
{name: "months"},
{name: "years"},
{name: "template"}
];
/*
Run the macro
*/
exports.run = function(basedate, days, months, years, template) {
//Make each date object.
if (basedate === "") {
var newdate = new Date();
} else {
var baseyear = basedate.substr(0,4);
var basemonth = basedate.substr(4,2);
var baseday = basedate.substr(6,2);
var newdate = new Date(Number(baseyear), Number(basemonth)-1,
Number(baseday), 0, 0, 0);
}
var new_year = Number(newdate.getFullYear())+Number(years);
var new_month = Number(newdate.getMonth())+Number(months);
var new_day = Number(newdate.getDate())+Number(days);
var output_date = new Date(new_year, new_month, new_day, 0, 0, 0);
var result = (output_date.getFullYear()*10000) +
((output_date.getMonth()+1)*100) + (output_date.getDate());
if(template === ""){
return result;
} else {
return $tw.utils.formatDateString(output_date,template);
}
};
})();
If this works, suggest you rename it (both in the comment at the top and
the tiddler title) to avoid confusion in the future.
