Age Calculation Formula: Age = Current Date - Date of Birth. Step-by-Step Method: Note your birth date (DD/MM/YYYY). Check today's date. Subtract birth year from current year (base age). Adjust for months: If birth month > current month, subtract 1 year and add 12 months. If birth month = current month, check days. Adjust for days: If birth day > current day, subtract 1 month. Example 1 - Simple Calculation: Birth: 15 May 1995. Today: 9 November 2025. Years: 2025 - 1995 = 30 years. Months: November (11) - May (5) = 6 months. Days: 9 - 15 = -6 days → Adjust to previous month. Final Age: 30 years, 5 months, 25 days. Example 2 - Complex Scenario: Birth: 31 December 2000. Today: 9 November 2025. Years: 2025 - 2000 = 25 years. Months: November (11) - December (12) = -1 → 24 years, 11 months. Days: 9 - 31 = -22 days → Adjust to 10 months. Final: 24 years, 10 months, 9 days. Age in Different Units: Days: Count all days from birth to today. Hours: Days × 24. Minutes: Hours × 60. Seconds: Minutes × 60. Example (30 years old): Days: ~10,957 days (30 × 365.25). Hours: ~262,968 hours. Minutes: ~15,778,080 minutes. Seconds: ~946,684,800 seconds. Quick Mental Math: Same birth date/month as today? Age = Current year - Birth year. Birthday already passed this year? Age = Current year - Birth year. Birthday not yet this year? Age = Current year - Birth year - 1.
Age Difference Calculation: Formula: Age Difference = |Date1 - Date2| (absolute value). Method: Calculate both persons' ages separately. Subtract younger age from older age. Express in years, months, days. Example 1 - Siblings: Person 1 (Elder): Born 1 Jan 1990 → Age: 35 years. Person 2 (Younger): Born 15 June 1995 → Age: 30 years. Difference: 35Y - 30Y = 5 years, 5 months, 14 days. Example 2 - Celebrity Comparison: Shah Rukh Khan: Born 2 Nov 1965 → Age: 60 years. Salman Khan: Born 27 Dec 1965 → Age: 59 years. Difference: 1 month, 25 days (SRK is older). Example 3 - Couple Age Gap: Husband: 30 years, 6 months. Wife: 27 years, 2 months. Gap: 3 years, 4 months. Detailed Calculation Process: Find older person (earlier birth date). Calculate full age of both persons. Subtract years: Older years - Younger years. Subtract months: Adjust if negative (borrow 1 year = 12 months). Subtract days: Adjust if negative (borrow 1 month = 28-31 days). Real-Life Use Cases: Siblings age gap (common 2-5 years in India). Couples age difference (average 2-4 years). Parent-child age (typical 25-35 years). Celebrity age comparisons. Age Gap Statistics India: Siblings: Average 2-3 years gap. Couples: 2-5 years gap most common (husband older). Parent-Child: Average 28 years (first child). Interesting Facts: Twins: 0 days (same birth date). Irish twins: <1 year gap (born same year). Generation gap: ~25-30 years (parent-child). Cultural Context: In India, husband typically 2-5 years older than wife. Arranged marriages often match similar ages (±3 years). Love marriages have wider age ranges acceptable.

Birthday Countdown Calculation: Formula: Days Until Birthday = Next Birthday Date - Today's Date. Step-by-Step Method: Note your birth date (DD/MM). Check today's date. Find next occurrence: If birth date already passed this year → Next year. If birth date not yet → This year. If today is birthday → 0 days (Happy Birthday!). Calculate difference in days. Example 1 - Birthday Ahead: Birth Date: 25 December. Today: 9 November 2025. Next Birthday: 25 December 2025. Days Until: 46 days. Example 2 - Birthday Passed: Birth Date: 15 May. Today: 9 November 2025. Birthday passed (May < November). Next Birthday: 15 May 2026. Days Until: ~188 days. Example 3 - Today is Birthday: Birth Date: 9 November. Today: 9 November 2025. Days Until: 0 days 🎉 Happy Birthday! Birthday Countdown by Month: January babies: ~2 months if in November (60 days). March babies: ~4 months (120 days). June babies: ~7 months (210 days). September babies: ~10 months (300 days). December babies: ~1 month (30 days). Fun Birthday Facts: Birthday Probability: 1/365 chance of sharing birthday with someone.

Korean Age System vs International Age: Korean age counting is DIFFERENT from rest of world! Korean Age Rules: Everyone born on Jan 1 = 1 year old (not 0). Everyone ages on New Year's Day (Jan 1), not birthday. You can be 1-2 years OLDER in Korean age! Example Calculation: Birth: November 9, 1995. International Age (2025): 30 years old. Korean Age Calculation: Born in 1995 = 1 year old on Jan 1, 1995. Every Jan 1 since = +1 year. Jan 1, 2025 = 31 years old in Korean age. Comparison: International Age: 30 years, 5 months. Korean Age: 31 years (1 year older!). Step-by-Step Formula: Korean Age = (Current Year - Birth Year) + 1. Example 1: Birth Year: 2000. Current Year: 2025. Korean Age: (2025 - 2000) + 1 = 26 years. Example 2: Birth Year: 1990. Current Year: 2025. Korean Age: (2025 - 1990) + 1 = 36 years. Special Cases: Born December 31: International Age: 0 years, 0 days. Korean Age: 1 year (since born in that year). Next day (Jan 1): International: 1 day old. Korean: 2 years old (turned 2 on New Year!). Real Example: Birth: Dec 31, 2023. Today: Nov 9, 2025. International Age: 1 year, 10 months. Korean Age: 3 years old! (Born 2023 = 1, Jan 2024 = 2, Jan 2025 = 3). Why Korean System Exists: Historical/cultural tradition. Respects the time in womb (~9 months). Community aging together (same year = same age group). Important in Korean culture (hierarchy by age). Korean Age in Practice: Used socially, informally. Legal age (driving, voting) = international age. Birth certificates show international age. School enrollment = birth year cohort (everyone same year = classmates). Recent Change (2023): South Korea officially switched to international age system (June 2023). Korean age still used socially/traditionally. Legal/official documents now use international age. Age Systems Comparison: International (Most Countries): Age = Current year - Birth year (adjust for birthday). Count from 0 at birth. Age on birthday. Korean (Traditional): Age = (Current year - Birth year) + 1. Count from 1 at birth. Age on New Year (Jan 1). Chinese (Lunar): Similar to Korean but based on Lunar New Year. Age + 1 on Chinese New Year (Jan-Feb). Vietnam (Traditional): Similar to Chinese (Lunar calendar-based). Other Fun Facts: In Korean, asking age is polite (determines speech level). Age determines social hierarchy (respect elders). "What year were you born?" more common than "How old are you?" (year determines cohort). Converting Korean → International Age: If birthday passed this year: Korean Age - 1 = International. If birthday not yet: Korean Age - 2 = International. Pro Tip: When in Korea, always clarify which age system! Job applications/legal forms = International age. Social settings = May use Korean age. When confused, just say birth year (everyone understands)!
