Browse dates and compare lunar dates, month and day cycles, and the current solar term. The almanac, seasonal markers and twelve double-hours have their own place.

04 / SKY NOTEBOOK
From historical sources to observations kept on your own device, explore the references and keep your own notes.
Search by phenomena such as eclipses, comets and guest stars, or start a text comparison from selected star officials or luminaries on the chart. Expand passages and context to check original dating, work, volume and source. A word match does not identify the same astronomical event.
Add text, photos you select, or a meridian chart image. Notes stay on your device, with no upload or cloud sync. Keep your own copies of important content before clearing App data or uninstalling.
Use a red light, dark-adaptation timer and telescope calculations, with a red or green interface. You can also set custom tools and historical-text URLs. External URLs open in a separate system browser window and cannot read the App's local records.
BEFORE YOU START
From dates to sky access.
Basic Gregorian and Chinese calendars, date cycles, solar terms, festivals, the almanac and anniversary reminders are directly available. Restricted sky content requires sign-in and the relevant sky entitlement.
Local calendar and almanac queries, anniversary records and local reminders do not require a continuous connection. Sign-in, entitlement refresh and App updates need a network connection. Available sky features also depend on the device's entitlement status.
Calculations use your selected observing city and time zone. Today follows the current time by default; other dates start at local noon. Expand the time controls to adjust the time and see the chart change.
