/v1/muhurta/vivah

Wedding muhurta composite score.

What this tells you

Scores one proposed wedding date and time. It checks 9 factors — tithi, weekday, Moon nakshatra, Sun sign (the Sun in Sagittarius, Capricorn or Pisces scores 0 and adds a warning), Rahu Kaal, Yamaganda, Durmuhurta, Panchaka and a Chandra Bala proxy — and turns the weighted total into a 0–100 score with a grade. Use this to check one candidate time; use /v1/muhurta/best-time to scan a date range.

Params: date, time, tz, lat, lon (plus optional ayanamsa). No birth details are used. ChandraBala here is a paksha proxy: full points in Shukla paksha, half in Krishna paksha. For chart-based checks, see /v1/muhurta/chandra-bala and /v1/muhurta/tara-bala.

Usage tips

How to use it

Show factor bars
One bar per factor, filled to score/weight. Users like to see exactly why a time is good or bad.
Warnings override grade
If `warnings` is not empty (for example Kharmaas or Rahu Kaal), show the warnings prominently even when the score looks fine.
Handle null warnings
`warnings` is null, not an empty array, when nothing is wrong. Treat both the same.
