## Default answer

Example with the default inputs (Year you were born 1976, Age on September 29, 2026) on the example date Tuesday, September 29, 2026: Born in 1976, on September 29, 2026 the age is 49 or 50: 50 if the birthday in 2026 has come, 49 if not.

## Inputs

| Key | Label | Description |
| --- | --- | --- |
| year | Year you were born | The year of birth, 1900 to 2100. |
| on | Age on | The date to find the age on. Today, unless you change it. |

## Outputs

| Key | Label | Description |
| --- | --- | --- |
| ages | Age in years | The age on the date: two numbers, the lower one before that year’s birthday. |
| after | From the birthday on | The age on the date if the birthday in that year has come. |
| before | Before the birthday | The age on the date if the birthday in that year is still to come. |
| detail | Which one | Which age applies when. |

## Method

Age = year of the date − birth year, once the birthday in that year has come; one less before it.

## Assumptions

- Age counts completed years, as in everyday use: you turn 1 on your first birthday.
- Without the month and day of birth, the age on most dates is one of two numbers; on the date’s year the birthday decides which.
- Only the year is known, so in the birth year itself the age shows as 0 even on a date before the birth.
- Someone born on February 29 has a birthday on February 28 or March 1 in other years; either way, the year difference is the same.

## Worked examples

1. year = 1976, on = 2026-09-28 gives after = 50, before = 49, ages = 49 or 50. Source: hand calculation: 2026 − 1976 = 50 after the 2026 birthday, one less before it.
2. year = 1976, on = 2030-01-01 gives after = 54, before = 53. Source: hand calculation: 2030 − 1976 = 54; on January 1 only a January 1 birthday has come.
3. year = 1976, on = 1976-12-31 gives after = 0, ages = 0. Source: hand calculation: 1976 − 1976 = 0.
