The Timing Chart is a screen that lists “world astronomical events” — such as solar and lunar eclipses, solar terms, lunar phases, sign ingresses of celestial bodies, retrogrades, void-of-course periods, and aspects forming between celestial bodies — over a specified period. Rather than showing transits to an individual’s natal chart, it lets you view the astronomical phenomena occurring on a global scale in chronological order.
Prerequisite: This screen operates independently of any individual natal chart (you can use it even without saved birth data). By default, it opens showing only “Void-of-Course” events. To view other event types, check the desired type filters and press the “Display” button.
Contents of this page
1. Screen layout
There are no tabs; it is a single, long vertical page. From top to bottom it is arranged as: control row (year, month, period, time zone, destination, Display / CSV buttons) → type filters → celestial body filter → results list. There is no graph display; results are always shown in table format.
2. Period and time zone settings
| Item | Description | Default |
|---|---|---|
| Year | Enter the year (1800–2200) directly | Current year |
| Month | Select the starting month from 1–12 | Current month |
| Period | 1 month / 3 months / 6 months / 12 months | 1 month |
| Time zone | JST(UTC+9) and 7 other major zones | Value saved in the settings screen (JST if none) |
| Destination | Which chart screen to send data to when a row is clicked (see Section 7) | Single (Natal) |
Simply changing the year, month, period, or type filters does not update the table. Be sure to press the “Display” button. Only time zone changes are reflected immediately in the table’s time display.
3. Type filters (7 types)
Only the checked types are calculated and displayed. If all are unchecked, the table will be empty.
| Type | Description | Default state |
|---|---|---|
| Eclipses | Solar and lunar eclipses | OFF |
| Solar Terms | The 24 solar terms (moments when the Sun passes each 15° point of ecliptic longitude) | OFF |
| Lunar Phases | New Moon, First Quarter, Full Moon, Last Quarter | OFF |
| Ingress | Sign changes of celestial bodies | OFF |
| Retrograde | Start of retrograde motion and resumption of direct motion | OFF |
| Void-of-Course | Void-of-course periods of the Moon | ON (this is the only type shown by default) |
| Aspects | Actual aspect formations between celestial bodies | OFF |
About aspect types: The aspects detected on this screen are the five types: Conjunction, Opposition, Trine, Square, and Sextile. Semisextile and Quincunx are not handled on this screen (void-of-course determination also uses only these five aspect types). Eclipses and aspects may take some time to calculate.
4. Celestial body filter
For the Ingress, Retrograde, and Aspects types, you can turn celestial bodies on/off individually using their symbol icons (all are ON by default). The available bodies are the 10 bodies from the Sun through Pluto, plus Chiron, the True Node, the Mean Node, Lilith, Ceres, Pallas, Juno, and Vesta — 18 bodies in total. Lunar Phases, Void-of-Course, Solar Terms, and Eclipses are not affected by this celestial body filter and are always displayed.
5. How to read the results table
| Column | Description |
|---|---|
| Date | Date in the selected time zone (with day of week) |
| Time | Time in the selected time zone |
| Type | Color-coded badge (Lunar Phases = yellow / Ingress = green / Retrograde = red / Void-of-Course = purple / Aspects = blue-gray / Solar Terms = orange / Eclipses = pink) |
| Details | Event details (displayed with decorated celestial body symbols, sign, degree, aspect type, etc.) |
The list is always sorted in ascending chronological order. Sorting by column header is not available. Changing the celestial body filter only narrows down the currently displayed data on the spot, but changing a type filter requires pressing “Display” again to request recalculation from the server.
6. Setting the reference location (linking with the input screen)
This screen itself has no map or location search input. The reference location is set from the “Location Input” tab on the input screen (top page).
- Open the “Location Input” tab on the input screen
- Choose a location using location search, a preset, or a map click (latitude, longitude, and time zone are filled in automatically)
- Press the “Save to Timing Chart” button
Once saved, you will automatically be taken to this Timing Chart screen, and that location will be used as the reference location from then on. If no place name was entered, it will be named “Map-Selected Location.” If no reference location has been set, the default preset location (Tokyo) will be used.
The reference location is used only for the time display and location information when opening a chart by clicking a row. Since the events themselves (eclipses, solar terms, aspect formations, etc.) are global phenomena, changing the reference location does not change the contents of the list itself. Also, since there is no field on this screen showing which location is currently set as the reference, please check on the input screen if you are working with multiple locations.
7. Opening a chart by clicking a row
Clicking a row in the results table opens the moment that event occurred in the chart screen selected as the “Destination” in the control row.
| Destination | Behavior |
|---|---|
| Single (Natal) | Passes the clicked moment as birth data to the Single Chart screen (if no name is entered, one is auto-generated in the format “Mundane Year/Month/Day”). |
| Bi-Wheel (Current) | Passes the data to the Bi-Wheel Chart screen as the outer wheel (transit) data. The inner wheel remains the existing natal data. |
| Tri-Wheel (Current) / Penta-Wheel (Current) | Passes the data as “current data” to the respective multi-wheel chart screens. |
The time passed is converted to the local time of the reference location, but the calculation of celestial body positions itself does not change.
8. CSV export
The “CSV” button downloads the currently displayed content (after filtering) as a CSV file. The columns are Date, Time, Type, and Details (4 columns), and the file name is “timing_開始年_開始月.csv.”
The type labels follow the display language, but some parts of the “Details” column (such as eclipse types or aspect names) may be output in English regardless. Please note that the content shown in the Japanese UI and the content shown when you open the CSV may differ in some respects.
9. Useful specifications to know
- There is no concept of orb: Aspect and void-of-course detection on this screen does not detect “periods within an allowed tolerance,” but only the exact moment the angle matches precisely, as a single event.
- Display spanning multiple periods: If you select 3 months or more for “Period,” events across multiple months are combined into a single chronologically sorted table.
- Printing: Using the browser’s print function is set up so that only the results list is printed, excluding the control row and filters.
- Persisted settings: The period, time zone, destination, and filter states are saved in the browser and carried over on your next visit (the year and month always reset to “today” each time).
