Modify dates for park tickets?

[JusticeDisney]

I understand that you can modify the dates for your park tickets up until the day before your start date, but does anyone know how far out into the future you can move your dates? For example, if necessary, could you push your tickets all the way into the next year, or is there an outside date to which you can’t go past?

Thanks!

In the past, I was able to move my tickets as far into the future as the schedule was open. I looked for the furthest date that did not require an additional amount.
