Date and time manipulation

✅ plusDays()

Adds days to a date.

LocalDate newDate = date.plusDays(10);

👉 Adds 10 days.

✅ plusWeeks()

Adds weeks to a date.

LocalDate newDate = date.plusWeeks(2);

👉 Adds 2 weeks (14 days).

✅ plusMonths()

Adds months to a date.

LocalDate newDate = date.plusMonths(3);

👉 Adds 3 months.

⚠ Important:
If the day does not exist in the new month, Java adjusts automatically.

Example:

LocalDate.of(2026, 1, 31).plusMonths(1);

Result → 2026-02-28

✅ plusYears()

Adds years to a date.

LocalDate newDate = date.plusYears(1);

👉 Adds 1 year.
