Building a budget form where I would like to pro-rate the budgeted amounts by calendar days in the year. Rather than asking the user to specify the start and end date for each calendar year to which the budget applied, I have built in only the overall start date and end date. The challenge has been calculating the number of days in each calendar year that fall within the range and adding these to separate numeric fields. I was thinking there might be a need to manufacture start and end dates for each year and then calculate from there using the code below. Anyone run into a similar issue or have any potential solution directions they could point me toward? Thanks in advance.
/transform fields to dates
var regularDate1 = new Date(EndDate.rawValue.replace(/-/g, "/"));
var regularDate2 = new Date(StartDate.rawValue.replace(/-/g, "/"));
// Get difference between dates in milliseconds
var milliseconds = regularDate1.getTime() - regularDate2.getTime();
// Define number of milliseconds in one day
var nMilliSecondsPerDay = 24 * 60 * 60 * 1000;
// Get difference in days
var days = Math.floor(milliseconds / nMilliSecondsPerDay) + 1;
//Display value in Numeric1 field
DaysYR1.rawValue = days;
