Real-Life Uses

Money Matters

"If I invest for 7 years starting today, when does my term end?"

History Buffs

"How many years between the first moon landing and Mars rover landing?"

Life Events

"What year will my newborn start kindergarten?"

Fun fact: The most common calculation is adding/subtracting 10 years - probably for decade anniversaries and "where will I be in 10 years" daydreaming!
