How to Calculate Age from Birth Year
The quick formula: Current Year − Birth Year = Age (or Age − 1 if the birthday hasn't occurred yet this year).
Born in 1990: 2026 − 1990 = 36 (after birthday) or 35 (before birthday)
Born in 2000: 2026 − 2000 = 26 (after birthday) or 25 (before birthday)
Born in 1985: 2026 − 1985 = 41 (after birthday) or 40 (before birthday)
