// नेपालीमा संक्षिप्त विवरण (Nepali Summary)
यो उमेर कैलकुलेटर नेपाली मिति (विक्रम संवत् - BS) र अंग्रेजी मिति (AD) दुबैमा आधारित भएर उमेर गणना गर्न सक्ने अत्याधुनिक उपकरण हो। यसले तपाइँको जन्म मिति र आजको मिति बीचको सटीक अन्तर वर्ष, महिना, दिन, हप्ता र घण्टामा देखाउँछ।
// Exact Age Calculation Logic
Computing chronological age requires reconciling complex calendar systems. Our calculator normalizes the input Bikram Sambat (BS) date of birth into its exact Gregorian (AD) equivalent through pre-computed astronomical solar transit mappings. Then, the precise difference is computed relative to the server/client current date, accurately accounting for varying month lengths and leap years.
// Worked Age Calculation Example
Suppose a user was born on Kartik 15, 2055 BS. Let's compute their age as of Baisakh 1, 2083 BS:
DOB in BS: 2055-07-15 Converted DOB in AD: November 1, 1998 Target Date in AD: April 14, 2026 (Baisakh 1, 2083) Difference: - Years: 2026 - 1998 = 28 years - Months adjustment: November to April = 5 months - Days adjustment: 13 days Resulting Age: 27 Years, 5 Months, 13 Days

// Frequently Asked Questions (बारम्बार सोधिने प्रश्नहरू)
How do I calculate my age in Nepali date (BS)?
Select the 'BS (Nepali)' calendar mode, enter your birth year, month, and day in Bikram Sambat, and click calculate. The calculator converts it to AD to calculate your exact age in years, months, and days.
Can I calculate my age using the Gregorian (AD) calendar?
Yes, simply toggle the calendar mode to 'AD (English)', input your date of birth, and get your precise age, total days, hours, and time until your next birthday.
Why does my age matter for official purposes in Nepal?
