Direct answer
The BRIGANCE age calculator prepares exact chronological age and a nearest-month display for the entered screening date.
The public Curriculum Associates calculator asks for birth date, screening date, and weeks premature for children under age two. This independent page keeps the unrounded age visible beside any derived display.

Formula and method
Exact age first; nearest-month display adds one month when the remaining day component is 16 or more; optional comparison shifts the birth anchor by entered premature weeks.
The calendar engine computes exact Y;M;D. The displayed nearest-month value carries into the next year when needed. The prematurity comparison adds the entered whole weeks to the birth-date anchor, then recalculates exact age; this does not determine whether a correction should be used.
To compare this result with another relevant method, open the Test Age Calculator. Calculate exact age for a test date and apply an explicitly selected reporting policy.
Worked example
January 1, 2024 to January 20, 2026 is exactly 2 years and 19 days. Under the disclosed 16-day nearest-month rule, the display is 2;01.
Leap years, month ends, and other edge cases
A 15-day remainder does not round up; a 16-day remainder does. Twelve rounded months carry to the next year. If the prematurity-adjusted anchor is later than the screening date, the comparison floors at zero.
Choose the right age result
Use this page only to prepare age fields. The current BRIGANCE manual or official calculator controls the accepted dates, age range, prematurity rule, administration, scoring, and interpretation.
Limits and responsible use
This independent tool is not affiliated with Curriculum Associates and does not administer or score BRIGANCE. The public page describes nearest-month age and a weeks-premature field; users must verify the current official workflow before recording a result.
Inputs, outputs and result meaning
Calculate exact chronological age, a nearest-month display, and an optional prematurity-adjusted comparison for a BRIGANCE screening date.
Inputs
- Date of birth
- Use the birth date exactly as recorded.
- Screening date
- Use the exact BRIGANCE screening date.
- Weeks premature
- Enter 0 unless the current BRIGANCE workflow asks for a prematurity adjustment. Supported units are value.
Outputs
- Nearest-month age
- This is the primary result. The display rule uses up to 0 decimal places.
- Exact chronological age
- The display rule uses up to 0 decimal places.
- Exact Y;M;D
- The display rule uses up to 0 decimal places.
- Prematurity-adjusted comparison
- The display rule uses up to 0 decimal places.
- Rounded up indicator
- It is displayed in yes/no. The display rule uses up to 0 decimal places.
- Weeks premature entered
- It is displayed in weeks. The display rule uses up to 0 decimal places.
The documented method is applied after the inputs are validated and normalized. Keep the result label, unit, selected mode, and stated limitations together when sharing the answer.
Frequently asked questions
Does this calculator score BRIGANCE?
No. It calculates and formats age only.
Why are exact and nearest-month ages both shown?
Keeping exact age visible makes the rounding step auditable.
When should weeks premature be entered?
Only when the current official workflow and the individual record require it.
Is the 16-day threshold guaranteed for every edition?
No. It is disclosed as this page's nearest-month policy and should be verified against current official materials.
