Name a fixed spot.
“Front left corner” is more useful than “the balcony”. Reuse the exact same zone name to compare its records.
NO FORECAST. JUST OBSERVATION.
Notice the light
you have.
Every corner tells a different story. Record when direct sunlight reaches your balcony, then compare the little places that make it yours.
02 / READ THE DAY
Your light, mapped.
0 observations
Totals merge overlapping intervals within each zone. They describe your records, not the full day’s exposure or a weather forecast.

Field notes
Opening a backup replaces your diary after confirmation. Device storage is optional; keep a file backup before clearing browser data.
SMALL HABITS, BETTER OBSERVATIONS
Keep gaps as gaps.
If you did not observe an hour, leave it unknown. An empty timeline means no observation was recorded, not that the spot received no sunlight.
Return in another season.
Your own records may change across dates. This journal calculates clock-time intervals only, not solar position, weather or plant suitability.
Times are recorded as local wall-clock minutes. On clock-change days this is not an elapsed-time measurement across a daylight-saving transition. Compare observations made on the same clock basis.
