To find a relative date 5 years in the future from a specific date, you can manually calculate it by adding 5 years to the given date. In this case, if the current date is 11th September, you can add 5 years to 11th September. September has 30 days, so you would add 5 years and take into account the varying days in September. To calculate it manually, you would add 5 years to the current year, which would take you to 2026. Then, considering the date is 11th September, you would skip to the same date in 2026. This would bring you to 11th September 2026.
