A leap month is the lunar calendar catching up, and charts diverge there. Rather than anoint one school orthodox, understand the divergence and settle the chart with real experience.
What This Question Is Really Asking
Leap-month births agonize over "which month am I," and sources conflict. The solution is not picking sides but knowing how the three schools cast, where they differ, and removing uncertainty through verification.
The Underlying Logic
Next-month school treats the whole leap month as the following month, since it is the "extra" month whose qi already moves on; many apps default to this.
Current-month school keeps it as the month it repeats, since solar terms and month-jian have not truly switched.
Split school (common in the Northern lineage) divides at day fifteen: days 1-15 follow the current month, 16+ the next; the monthly lord also splits, a compromise with strong practical hit rate.
The three can shift the Life Palace, major stars and even natal transformations, so never choose on a hunch: cast both adjacent months and verify against personality, tendencies and the years of major turning points—the chart that matches more events wins.
A Step-by-Step Way to Read It
- Confirm you were born in a lunar leap month, which month it repeats and whether your day is in the first or second half
- Cast two full charts for the adjacent months and mark differences in Life stars and natal transformations
- Roughly screen with long-term traits: personality, constitution, family structure
- Then test three to five past major events (schooling, moving, relationships, job changes) by year
- Whichever chart matches more decade/year events is your confirmed chart
- After confirming, stick to one set of rules instead of switching charts per question
Three Common Mistakes
Mistake 1: Insisting one school is absolutely right while leap casting genuinely diverges
Mistake 2: Casting only one chart and never verifying, blaming the system instead of confirming
Mistake 3: Cherry-picking favorable readings between two charts and losing objectivity
Back to Your Own Chart
A leap month is not a dead end but a reminder to verify the chart. Place two charts side by side, let real experience vote, and once settled stop agonizing over the month—later accuracy comes from a stable chart and ongoing checks.
Reading Order
- Cast the natal chart first and locate the palaces and major stars tied to casting a leap-month birth before judging anything
- Open the triple-direction of those palaces and count the auspicious, malefic and assistant stars separately
- Check where the natal Four Transformations land to set the chart's baseline tone
- Read the decade-limit transformations to see whether the casting a leap-month birth line is activated in this stage
- Then read the annual transformations and the year's palace to pin down this year's trigger and timing
- Layer natal, decade and year before concluding, then decide how to act rather than labeling good or bad
