Which formulas return a date one year after a sale?

The correct approach to returning a date one year after a sale is demonstrated in the formula AdjustYear([Sale Date], 1). This function specifically adjusts the year of the given date by the number of years provided as a parameter. In this case, it effectively takes the original sale date and adds one year to it, yielding the desired date exactly one year later.

Option A is not applicable because simply adding a year through arithmetic like in [Sale Date] + Years(1) might not work as intended since the behavior of date addition could vary depending on how years are handled in the context of leap years and month-end scenarios.

AdjustMonth([Sale Date], 12) would yield a date twelve months later, which is not equivalent to one year due to variations in month lengths.

Lastly, using [Sale Date] + Days(365.25) could provide an approximation that generally works out to a year, accounting for leap years; however, it is not precise because not every year has exactly 365.25 days, and this can lead to inaccuracies based on how the days are computed across different months and leap years.

Thus, AdjustYear([Sale Date], 1) is the most accurate and reliable method for calculating a date one year
