Interval rectification
Clients often remember a window, not an exact time: “somewhere between six and ten in the morning.” Set the window and get a table of what stays stable and what changes, with exact moments for signs, houses, aspects and angles.
What stays stable
Planets that keep their sign and house, stable aspects and angle positions. These hold for any time inside the window.
What changes
Exact minutes of sign and house changes, orb entry and exit, exact aspects, and ASC, MC and cusp changes. All in one chronological table.
PDF for the client
A ready PDF with the interval, stable factors, angle segments and the change list. Attach it to a consultation.
What the result looks like
Example window 06:00–10:00 with a 5-minute step. The rows show changes only; stable factors are listed separately.
| Time | Event | Object | From | To |
|---|---|---|---|---|
| 06:40 | house change | Moon | 7 house | 6 house |
| 07:38 | angle change | MC | Libra | Scorpio |
| 08:25 | angle change | ASC | Sagittarius | Capricorn |
| 09:25 | leaves orb | Moon trine Pluto | in orb | out of orb |
Values in the example are illustrative and show the format, not a specific chart.
Who it is for
- Astrologers who rectify manually and spend hours comparing charts.
- Consultants who need to show clients which conclusions are stable and which depend on time.
- Students: the table shows visually how time changes houses, angles and aspects.
The tool is included in Praktik and Praktik + AI. This is interval analysis, not a full event-based rectification: it does not replace a biography review, but removes the routine chart sweep.
Frequently asked questions
How is this different from full rectification?
Full rectification compares time candidates against life events: marriage, moves, work, crises. This tool computes an astronomical slice of the window: what is stable and what changes. It is a fast first step before choosing candidates for event analysis.
How precise are the change moments?
The calculation uses ephemerides at the step you choose. Sign, house or exact aspect moments are refined to the minute. A smaller step means more calculation points and a more precise table.
