Luck start: 8 years, 4 months and 15 days, on 16 May 2034. The first Luck Pillar is 丁亥, covering 2034–2043 and displaying ages 9–18. This age column is not an elapsed duration.

Time convention: enter the time in UTC+8. Longitude correction uses (longitude − 120°) × 4 minutes. The engine does not include the equation of time or automatically convert historical time zones or daylight saving time. Choosing an overseas city only sets its longitude.
