Unified Map · Clock · Compass
One physical 512-state cycle. Two complete views. Pick your poison: Decimal 512 or Octal 1000₈. Map, clock, compass, coordinates and phase labels switch together. No mixed notation.
888 is the design motif, not an octal numeral. Octal has eight digit states, 0 through 7. The quantity eight is written 10₈; the completed 512-state A8 whole is written 1000₈.

1. Exact World Grid — computed geometry
Measurement surface rule: this map is generated from the coordinate mathematics, not from decorative artwork. Decimal and octal modes change labels only. Coastline context, grid positions, city markers and great-circle routes stay fixed.
Octal: 000₈ → 200₈ → 400₈
Opposite meridian = 256
Shortest route is still computed on the sphere.
2. A8 Coordinate & Travel Workbench
A8 first. Click the map to capture two positions, or enter A8 coordinates directly. The first map click fills POINT A; the second fills POINT B. Conventional coordinates are shown afterward only as a legacy comparison.
The 153-city shelf remains a nearby reference finder. City-center coordinates are approximate reference points, not boundaries.
Select a general reference speed. The A8/NAV distance does not change when the travel method changes.
CAR 48 is the reference speed while driving. If you plan to drive only half of each 32-hour A8 day — 16 A8 HOURS — use half the moving speed as the effective whole-day journey rate. For CAR 48, enter CUSTOM 24. 48 × 16/32 = 24 A8/NAV per A8 HOUR.
Shortest great-circle model: A→B uses the shortest spherical surface arc. Longitude 0 / 512 is one meridian, so the route crosses that wrap whenever doing so is shorter. Shortest surface angle is always 0 → 256 A8 states; shortest surface distance is always 0 → 16384 A8/NAV. At exactly 256 the points are antipodal and multiple equal shortest great-circle routes exist.
3. Compass
The compass gives the bearing. A8 Navigation carries that direction forward into position, route, distance, speed, elapsed time and arrival.
Conventional clockwise orientation remains unchanged. Decimal mode cardinals: N 0/512, E 128, S 256, W 384. Octal mode: N 000/1000₈, E 200₈, S 400₈, W 600₈.
INTERACTIVE COMPASS: move a mouse around the compass face, or drag a finger across it on a touch screen. Leave the compass or lift your finger and it returns North.
Same physical directions
| Direction | Decimal 512 | Octal 1000₈ |
|---|---|---|
| N | 0 / 512 | 000₈ / 1000₈ |
| NE | 64 | 100₈ |
| E | 128 | 200₈ |
| SE | 192 | 300₈ |
| S | 256 | 400₈ |
| SW | 320 | 500₈ |
| W | 384 | 600₈ |
| NW | 448 | 700₈ |
| N complete | 512 → 0 | 1000₈ → 000₈ |
4. One Ruler Everywhere
Longitude, clock phase and compass bearing are the same complete 512-state turn expressed in the selected notation. Latitude is a half-turn from North Pole to South Pole, so it ends at 256 decimal / 400₈.

Shared outer phase ruler
Clock fields follow the same mode
The outer day phase and the HH:MM:SS decomposition describe the same 32×64×64 = 2¹⁷ daily states.
8. What Never Changes
9. City & Route Atlas
Quick reference: six familiar cities show how the same Earth can be expressed in A8 hour sectors and A8 coordinates. This is a reproducible geometry demonstration, not an operational travel or navigation service.

Quick reference only · six familiar city centers demonstrate the A8 coordinate ruler on the same Earth. This is not an operational travel-routing dataset.
Route reference
| Route | A8/NAV distance | Elapsed travel reference | Legacy geometry check |
|---|
Length identity: 1 A8/NAV = 1 A8/41. /41 is the binary ladder address; NAV is the Earth-navigation name for the same distance across land or water.
A8 elapsed time is shown first. 1 A8 hour = 45 legacy minutes, so legacy elapsed hours × 4/3 = A8 hours. A day remains the same physical full-day interval: 24 legacy hours = 32 A8 hours. Local clock changes and date-line changes do not alter elapsed travel time.
Tokyo ↔ Los Angeles — sourced navigation benchmark
Air — current schedule example
HND → LAX: (10:00 legacy elapsed)
NRT → LAX: (9:45 legacy elapsed)
Derived from Japan Airlines' published March 29–October 24, 2026 Tokyo→Los Angeles schedule and the applicable JST/PDT offset. Schedule times can change; this is an example, not a definition of A8 time.
Sea — navigation benchmark @ 20 kn
Great-circle ≈ 4,800 nmi: (240 legacy h) = 10 days
Rhumb-line ≈ 5,100 nmi: (255 legacy h) = 10.625 days
MOL's navigation example gives approximately 4,800 nmi great-circle and 5,100 nmi rhumb-line distance between Los Angeles and Tokyo. MOL also notes that actual routing considers weather, sea conditions and tidal currents.

Separate presentation layer only: 32 equal longitude sectors, each 16 A8 longitude units wide. This helps connect the map to the 32-hour daily structure without changing the underlying coordinate grid.
