Lunar return chart after a given date.

Request

All requests require an Authorization header with your dv_live_* API key.

example request

curl "https://api.lifeastroapi.com/v1/western/returns/lunar?date=1990-01-15&tz=Asia%2FKolkata&lat=19.076&lon=72.8777&from=2026-04-25T00%3A00%3A00Z&time=10%3A30" \
  -H "Authorization: Bearer YOUR_API_KEY"

Query parameters

Checked against the API: a parameter is marked required when the request fails without it.

Name	Required	Example	Description
`date`	yes	`1990-01-15`	Birth date (YYYY-MM-DD).
`tz`	yes	`Asia/Kolkata`	Birth place timezone: IANA name (Asia/Kolkata) or UTC offset (+05:30).
`lat`	yes	`19.076`	Birth place latitude in decimal degrees.
`lon`	yes	`72.8777`	Birth place longitude in decimal degrees.
`from`	yes	`2026-04-25T00:00:00Z`	Search-start moment for the next lunar return (RFC3339 UTC). Required — no implicit "now"
`time`	no	`10:30`	Birth time (HH:MM, 24-hour, local). Defaults to 12:00.
`house_system`	no	—	House system. Phase 2c supports placidus (default), whole_sign, koch, equal. Placidus and Koch reject \|lat\| > 66° (geometrically undefined inside polar circle); Whole Sign and Equal accept any latitude.
`relocate_lat`	no	—	Optional relocation latitude for relocated returns. Both relocate_lat and relocate_lon must be provided together.
`relocate_lon`	no	—	Optional relocation longitude for relocated returns. Paired with relocate_lat.
`rulership`	no	—	Sign-rulership scheme for House / ASC / MC ruler emission. modern (default) uses post-discovery rulers (Pluto-Scorpio, Uranus-Aquarius, Neptune-Pisces). traditional uses the classical 7-planet scheme (Mars-Scorpio, Saturn-Aquarius, Jupiter-Pisces) — outer planets are not assigned ruling signs.
