Fun Facts
“So… am I 10,000 days old yet?”

Espresso-Shot FAQ ☕️
| Question | Snack-size Answer |
|---|---|
| Core formula? | Age = Today – Birth date (in a date-diff function). |
| Leap-year accuracy? | Good calculators count 29 Feb. Yes, yours should. |
| Why bother? | Visas, insurance, zodiac memes, bragging rights. |
1 | Anatomy of an Age Calculator
| Field | What You Enter | Behind-the-Scenes Math (ISO 8601 style) |
|---|---|---|
| Birth date | 1999-07-14 | Stored as epoch days. |
| Target date | Today (default) or future job app deadline | Epoch – epoch = age interval. |
| Output | Years · Months · Days + weekday | Uses period and duration libraries. |
Dev hack: In JavaScript,
const age = new Date().getFullYear() - dob.getFullYear();gets a ballpark—but for payroll accuracy, callIntl.RelativeTimeFormat.
2 | Step-by-Step Example (No Code Needed) 🌪️
Write the two dates
Birth: 24 March 2005
Today: 19 May 2025
Count full years first
2005 → 2025 = 20 yearsAdjust months
March → May = 2 monthsFinish with days
24 → 19 May = If target day < birth day, borrow last month’s days.
• April has 30 days → 30 – 24 + 19 = 25 daysAge = 20 years 2 months 25 days. 🎉
