Steps

  1. 1Collect authoritative birth date source—passport versus self-reported survey.
  2. 2Compute as-of reference date explicit in audit logs.
  3. 3Store minimal PII; redact paste buffers on shared kiosks.
  4. 4Pair local legal counsel interpretation for edge cases near midnight birth.

Examples

  • Sports league divisions confirm player eligibility cutoffs.
  • Insurance quoting adjusts premiums at birthday boundaries.

What to avoid

  • Using timezone shifts that move birth instant across calendar dates.
  • Confusing biological age with policy contract age definitions.
  • Caching ages without recomputing on birthday server cron.
