Monthly Parallels - Declination contacts for an entire month
post_astrology_parallels_monthlyGet every parallel and contraparallel of declination that perfects during a given month, across the 13 non-lunar Western bodies: the Sun and Mercury through Pluto, both lunar nodes, Chiron and Black Moon Lilith. A parallel is two bodies at the same declination and reads much like a conjunction; a contraparallel is equal and opposite declinations and reads much like an opposition. Neither depends on zodiacal distance, so they surface connections an aspect table cannot show, which is why traditional and modern practitioners read them alongside aspects. Declinations are geocentric, matching what an ephemeris publishes. Returns the exact date and time of closest approach in your timezone with both declinations. The Moon is excluded because its declination swings the full range every month and would bury the slow pairs. Omit year and month to get the month in progress, so a published calendar stays current without a redeploy. Essential for declination work, out-of-bounds tracking, monthly forecast copy, and electional timing. Monthly parallel calendar API, declination aspects, contraparallel ephemeris. Verified against NASA JPL Horizons.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| orb | No | How far from exact still counts, in degrees. The traditional orb for a declination contact is tighter than for a zodiacal aspect because declination changes slowly. Defaults to 1.5. | |
| lang | No | Response language (BCP 47). Supported: en, tr, de, es, hi, pt, fr, ru, zh-Hans, zh-Hant. Defaults to en. Coverage varies by domain, and a field with no translation in the requested language returns English. | en |
| year | No | Year for the declination calendar (1551 to 2649). Defaults to the current year (UTC). | |
| month | No | Month number (1-12). Defaults to the current month (UTC). | |
| compact | No | Set true for the same data in a compact shape: arrays of same-shaped objects arrive columnar as {"__cols":[names],"__rows":[[values]]}. Lossless, typically 40 to 52 percent fewer tokens. | |
| nodeType | No | Lunar node convention. "mean" is the smoothed average node, which always moves retrograde; "true" is the osculating node, which tracks the real perturbed node, oscillates up to about 1.5 degrees either side of the mean on a 173-day cycle, and can briefly turn direct. Neither is more correct and they almost always fall in the same sign. Applies to the North and South Node. True is the osculating node and the default, because it is what most Western chart software reports; mean is the smoothed node preferred by several evolutionary schools, so pass "mean" to match one. Nothing else in the chart changes, and the two agree on the sign except when the node sits within about 1.8 degrees of a cusp. Defaults to "true". | true |
| timezone | No | Timezone: an IANA name (e.g. "America/New_York", "Europe/London", or `cities[0].timezone` from /location/search) or decimal hours from UTC (e.g. -5 for EST, 5.5 for IST). An IANA name is resolved once, at the start of the window, and that offset applies to every time in the response. Event dates and times are reported in this zone, which is what makes a published calendar read correctly for its audience. Defaults to 0 (UTC). |
