Adding Months to a date

let theYear := year(Date);
let theMonth := month(Date);
let theDay := day(Date);
let addMonths := 36;
let newDate := date(theYear, theMonth + addMonths, theDay);

"Carefull for the end of febuary tough";
newDate

One simpler approach:

Fields:

- Date (date)

- Number of Months (number)

and the formula:

date(year(Date), month(Date) + number('Number of Months'), day(Date))

If it's a pair number like 36, there is no problem except if the start date is over day 28 and it lends in febuary. That is because month() are caculated in 31 days. Let say you add 39 months to the 2020/01/31 you are going to get 2023/04/01 and that is 40 months. In the case of loans and leases management that could potentially be a problem. So be carefull with a simple approach.

Both codes produce the same result. I just meant that in this case you don't need the variables.

If you want to get accurate about the end dates of any months, try this simple formula contaning at least one variable:

let overDate := date(year(Date), month(Date), 31);
if month(overDate) > month(Date) then
overDate - day(overDate)
else
overDate
end

Then if you want to make accurate projections over many months, you will need more variables and a loop.
