The Java library actually supports this case.
It may not have the convenient "years" method directly, but you can add an arbitrary unit of time quite easily
Example with duration:
Duration.of(1, ChronoUnit.YEARS)
Example with datetime:
today.plus(2, ChronoUnit.YEARS)
It even supports decades, centuries, eras and half days :-)
For those curious about how it handles leap years:
var leapDay = LocalDate.of(2024, 2, 29)
leapDay.plus(1, ChronoUnit.YEARS);
// ==> 2025-02-28
var lastYear = LocalDate.of(2023, 3, 1);
lastYear.plus(1, ChronoUnit.YEARS);
// ==> 2024-03-01
var lastFeb = LocalDate.of(2023, 2, 28);
lastFeb.plus(1, ChronoUnit.YEARS);
// ==> 2024-02-28
var firstFeb = LocalDate.of(2024, 2, 1);
leapDay.with(TemporalAdjusters.lastDayOfMonth());
// ==> 2024-02-29
- rfoo 3y agoThanks! It does this according to doc: This method adds the specified amount to the years field in three steps: * Add the input years to the year field * Check if the resulting date would be invalid * Adjust the day-of-month to the last valid day if necessary TIL. I didn't know that Java had a builtin calendar (instead of datetime) library.
