Birth Time Rectification

The lagna, the first house of the self, moves through a sign in about two hours. Navamsa changes faster, on the order of a dozen minutes, because it is the ninefold division. A clock error that seems small can change the seventh house of marriage in Navamsa and the tenth lord of career in Rashi. The zone offset is applied before the Julian day. Daylight saving is a common reason a hospital time and a civil time disagree. Rectification exists because those errors are real. It is a test of candidates, not a recovery of a lost document.

Candidate times are compared with dated events: marriage, a parent's death, a move abroad, a job. Marriage should touch the seventh lord's period. A foreign move should be able to touch the twelfth house of loss and foreign residence. The Moon's nakshatra must fit the Vimshottari sequence those events imply. If every candidate fails, say the time is unknown. Do not crown the candidate that flatters the native. The eighth house is longevity. Do not use a death prediction as a puzzle piece. Use events that already happened, and do not invent the years.

A rectified clock for the wrong city is still wrong, because the offset differs. Jyothish SI geocodes the city. A free kundli shows the lagna the current data produce. Paid divisionals make Navamsa easier to compare. No price is stated. The result of rectification should be stated as a hypothesis with a range. Love versus arranged marriage is a later question, about the fifth and seventh, and it should not be used backward to force a lagna.
