How is a daily rashifal calculated?
In short
How is the daily rashifal on this site calculated?
We compute the sidereal longitudes of the Sun and Moon for local noon using the Lahiri ayanamsa, then count the Moon's house from each rashi. Classical gochar rules assign favourable and difficult results to each house, and the nakshatra lord adds the day-to-day variation. Every position used is printed on the page.
The calculation
The Moon's apparent geocentric longitude is computed from a truncated lunar theory, and the Sun's from standard low-precision solar coordinates. Both are converted to the sidereal zodiac by subtracting the Lahiri ayanamsa for that date. The results agree with published ephemerides to within a few arcminutes, which is far more precision than a rashi or nakshatra assignment requires.
We sample at local noon in the market's timezone — Asia/Kathmandu for Nepali, Asia/Kolkata for Hindi and English — so a reading changes at the correct local date rather than at UTC midnight.
The interpretation
The Moon's house counted from your rashi drives the daily reading. Houses 1, 3, 6, 7, 10 and 11 are favourable for the Moon in classical gochar; the 8th, Chandrashtama, is the most difficult. Weekly and monthly readings use the Sun's house instead, because the Sun changes rashi about once a month.
Each life domain is scored from where the transit falls relative to that domain's own bhava, which is why love, career, money and health do not all move together. The Moon's nakshatra lord supplies a second layer that changes roughly daily, so two consecutive days do not read identically even while the Moon sits in one rashi.
Verifying it
Every reading prints the positions it used: the Moon's rashi and nakshatra, the Sun's rashi, the tithi and paksha, and the gochar house. Compare any of them against a panchang you trust. If they match, the astronomy is right; what you do with the interpretation is a separate question, and an open one.
