How It Works

Age Calculation

We calculate your exact age by comparing your birth date with a reference date (today, by default). The calculation accounts for leap years and varying month lengths.

Age Calculation Formula:

Age (years) = ⌊(Reference Date - Birth Date) ÷ 365.25⌋
Age (months) = ⌊(Remaining Days) ÷ 30.44⌋
Age (days) = (Remaining Days) mod 30.44

Zodiac Sign

Your zodiac sign is determined by your birth month and day. There are 12 zodiac signs, each with a specific date range.

Zodiac Lookup:

If (Month = 3 AND Day ≥ 21) OR (Month = 4 AND Day < 20) → Aries ♈
[... continues for all 12 signs]

Retirement Countdown

Retirement age varies by country. We provide default retirement ages based on official government data for your region. You can also customize your target retirement age.

Retirement Calculation:

Retirement Date = Birth Date + Retirement Age (in years)
Countdown = Retirement Date - Today
