Each band shows the days of the month on which that condition held. Days are read at 12:00 UTC. The bands carry no favourable or adverse colour, deliberately: events falling more often inside a window is not good news.
Tested condition
Within 18 days either side of an eclipse
1–31 January 1973
In force on 31 of the month's 31 days.
What already happened while this same condition held — counted across the whole record:
Tested against: geophysical events, political events, market events. Categories this condition was not tested against are left out rather than shown as a zero; that restriction is this platform's stated configuration, not a statement of the texts.
Classical basis. Proximity to an eclipse season — the luminaries near the nodal axis. The eighteen-day span is Horā’s stated convention.
Eclipse
Solar eclipse
4 January 1973
4 January 1973, maximum at 15:46 UTC.
Not tested by the record
None of the seven tested conditions is keyed to this event on its own, so the record offers no count for it. It is listed because it is a fact of this month's sky, and no number is attached to it. The tested window an eclipse opens appears above as its own band, and the counts are given there.
Classical basis. The eclipse maximum comes from the same astronomical routine this platform's eclipse catalogue was built with. The time is UTC.
Tested condition
Within 14 days after an eclipse
5–31 January 1973
In force on 27 of the month's 31 days.
What already happened while this same condition held — counted across the whole record:
Tested against: geophysical events, political events, market events. Categories this condition was not tested against are left out rather than shown as a zero; that restriction is this platform's stated configuration, not a statement of the texts.
Classical basis. Bṛhat Saṁhitā, the eclipse chapters: effects are said to follow an eclipse. The fourteen-day window is Horā’s stated convention, not the text’s number — the text gives no count of days.
Tested condition
Maṅgala and Śani within 10° of conjunction or opposition
7–31 January 1973
In force on 25 of the month's 31 days.
What already happened while this same condition held — counted across the whole record:
Tested against: geophysical events, political events, market events. Categories this condition was not tested against are left out rather than shown as a zero; that restriction is this platform's stated configuration, not a statement of the texts.
Classical basis. Classical mundane doctrine: the mutual affliction of Maṅgala and Śani marks strife and scarcity. The 10° orb is Horā’s stated configuration; the texts describe, they do not measure in degrees.
Tested condition
Budha retrograde or combust
9–31 January 1973
In force on 23 of the month's 31 days.
What already happened while this same condition held — counted across the whole record:
Tested against: market events. Categories this condition was not tested against are left out rather than shown as a zero; that restriction is this platform's stated configuration, not a statement of the texts.
Classical basis. The price (argha) and motion chapters of the Bṛhat Saṁhitā link anomalous motion of the significator of trade to disturbance in prices. Retrogression and a 12° combustion orb are Horā’s stated operationalisation.
Tested condition
Graha-yuddha — two tārā-grahas within 1°
18 January 1973; 31 January 1973
In force on 2 of the month's 31 days.
What already happened while this same condition held — counted across the whole record:
Tested against: geophysical events, political events, market events. Categories this condition was not tested against are left out rather than shown as a zero; that restriction is this platform's stated configuration, not a statement of the texts.
Classical basis. Bṛhat Saṁhitā, the graha-yuddha chapter: a war between planets is said to distress nations, and the people of the defeated planet to suffer.
Eclipse
Lunar eclipse
18 January 1973
18 January 1973, maximum at 21:17 UTC.
Not tested by the record
None of the seven tested conditions is keyed to this event on its own, so the record offers no count for it. It is listed because it is a fact of this month's sky, and no number is attached to it. The tested window an eclipse opens appears above as its own band, and the counts are given there.
Classical basis. The eclipse maximum comes from the same astronomical routine this platform's eclipse catalogue was built with. The time is UTC.
Ingress
Guru enters Makara
25 January 1973
25 January 1973 — first found in the new rāśi at 12:00 UTC on this day.
Not tested by the record
None of the seven tested conditions is keyed to this event on its own, so the record offers no count for it. It is listed because it is a fact of this month's sky, and no number is attached to it.
Classical basis. An ingress is the crossing of a sidereal (Lāhirī) rāśi boundary, sampled at 12:00 UTC each day. Only Maṅgala, Guru, Śani and Rāhu are shown; Budha and Śukra change sign every few weeks and no tested condition is keyed to their ingress.
