There are two common reasons for differences between Human Design charts with the same birth data:
1. A mistake during data entry
Double-check the birth data as differences between chart creation web forms can cause mistakes. Take particular note of the date and month configuration, as Europeans prefer day/month while North Americans use month/day.
2. A difference in UTC, Time Zone, or Daylight Saving data
It’s possible that the charts were created by chart calculators using different Time Zone, UTC offset, and Daylight Saving Time data, which could result in differences. Charts created at maiamechanics.com use TZ data which is considered highly accurate and reliable.
If you continue to have concerns, we recommend researching the data of your place of birth on the date of your birth. You can compare your discoveries with the data displayed under chart properties > Birth data.
If you discover that a change needs to be made, please send us your source of information, and we can manually update our data.
