Local calculation · optional AI reading

Eligibility: this free calculator currently accepts birth details recorded in the Asia/Manila timezone, within its stated research range.

Your result shows available chart labels and a simple count of visible Wood, Fire, Earth, Metal, and Water labels; it is not a personal reading or assessment.

Birth details, with uncertainty visible.

For this free calculation, your birth details stay in this browser: the calculator does not save or transmit them, and does not place them in a URL.

Date and time of birth

Supported dates: 1901-01-01 through 2050-12-31. Future dates are not accepted.

Date of birth Required. Use the calendar date shown on the birth record.

Time of birth Required when known. Enter the time shown on the local clock, not a converted time.

I do not know the time of birth

Unknown time checks the whole local date. The hour pillar and multiple other fields can be withheld.

Birthplace (Manila only)

This free calculator currently supports birth details recorded in Manila, Philippines, using Asia/Manila.

Birthplace timezone Manila is the only enabled option. The calculator does not adjust another birthplace to Manila.

Unknown time can withhold the hour pillar and multiple other fields.
A late-Zi time, 23:00–23:59, withholds the day and hour pillars.

Methodology and limitations

This local adapter returns package calculation output using a sect-2 local-midnight convention. Package output is not independent astronomical validation; the stated research support is limited to the supported range and Asia/Manila conditions.

Asia/Manila is the only supported timezone in this first slice; an invalid IANA name is a validation error.
Supported Gregorian research range is 1901-01-01–2050-12-31; future dates are rejected.
Runtime IANA historical-offset handling must resolve uniquely at UTC+08, or calculation is blocked rather than guessed.
No true-solar-time correction is applied.
Unknown time evaluates the whole local date and withholds non-invariant year, month, or day fields. Known-minute inputs near a term boundary can withhold year or month when the tolerance window changes them.

Glossary

Pillar: A displayed stem-and-branch pair for year, month, day, or available hour.
Day Master: The displayed day stem, shown with its raw element and polarity label.
Visible-element count: One main element per displayed stem and branch. Hidden stems and strength are not counted.
Withheld: A field not shown because it changed across the supported uncertainty window.

Raw counts are not a strength score, medical claim, missing-element prescription, scientific finding, or prediction.
