Two chart apps can display different monthly Life Palaces for the same person. Before choosing the result that sounds better, check three settings: which lunar month contains the event, how Dou Jun is calculated, and whether the app labels natal or rearranged monthly palaces.
Keep the date, time zone, birth time convention, and school fixed. Compare the branch and month sequence, not only the translated palace name. A different transformation table is a separate setting and should be recorded separately. Once the mapping is clear, relate the monthly palace to the natal topic and the decade and annual background. Use schedules and documents to decide what to do.
