Solution: Birth date: July 4, 1990\nReference: March 24, 2026\nYears: 2026 - 1990 = 36, but March < July, so 35 years\nMonths: March - July = -4 + 12 = 8 months\nDays: 24 - 4 = 20 days\nTotal days: ~13,047 days\nTotal weeks: ~1,863 weeks\nTotal hours: ~313,128 hours
Result: 35 years, 8 months, 20 days | 13,047 total days | ~939 million heartbeats
