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 14 days after an eclipse
1–24 November 1920
In force on 24 of the month's 30 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
Within 18 days either side of an eclipse
1–28 November 1920
In force on 28 of the month's 30 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.
Tested condition
Budha retrograde or combust
6–25 November 1920
In force on 20 of the month's 30 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.
Station
Budha turns retrograde
6 November 1920
6 November 1920 — the change of direction is first seen 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. A station is read from the change of sign of the body's speed, sampled at 12:00 UTC each day. No time finer than the day is computed.
Eclipse
Solar eclipse
10 November 1920
10 November 1920, maximum at 15:52 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
Śani enters Kanyā
17 November 1920
17 November 1920 — 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.
Ingress
Maṅgala enters Makara

Station
Budha turns direct
