Tasks custom date

中文

Automatically write created, completion and cancelled timestamps when tasks change state. Supports custom state transitions, configurable field templates, a unified time format, creation-time suggestions, and multiple languages.

Features

Task interception strategy

• The setting "Interception trigger tag/text" defaults to #custom.
• Only tasks containing the tag/text are intercepted for timestamp writes and state transitions.
• Leave the input empty to intercept all tasks (global mode).

State transition engine

• Fixed base states: incomplete [ ] and done [x].
• Add any number of custom intermediate states with a name and icon character; list order defines the click cycle.
• Transition scope:
  • Default "only specified tag/text tasks transition": only tasks containing the transition trigger tag/text cycle through states.
  • "All tasks transition": all tasks cycle through states.
  • "No transition": clicking toggles only between incomplete and done; intermediate states are not involved.
• The transition trigger tag/text is independent of the interception trigger tag/text.
• Unconfigured state icons (for example [o]) fall back to incomplete [ ] when clicked.
• The state row shows the transition path, for example [x] ( ◔ ω◔) ⇨ [/].

Field formats and writes

• Each state has a format template; {{time}} is replaced with the current time when the task enters that state.
• Templates without {{time}} are written literally and do not append a timestamp.
• All time fields share the "Time format" setting: YYYY-MM-DDTHH:mm:ss, YYYY-MM-DD HH:mm, YYYY-MM-DD, or a custom moment.js format.
• A live preview is shown below the custom format input, with the moment.js formatting guide.
• "Always write created time": when enabled, a missing created time is written whenever a task in any state is clicked; existing created time is never overwritten.

Examples:

• [created:: {{time}}] → [created:: 2026-08-08T04:15:04]
• [completion:: {{time}}] → [completion:: 2026-08-08T04:15:04]
• [cancelled:: {{time}}] → [cancelled:: 2026-08-08T04:15:04]

Created time suggestions

• Typing the suggestion trigger character (default space) in a task line shows a created time suggestion.
• The suggestion uses the incomplete state's format template.

Commands

• Create or edit task: create or edit a task
• Toggle task done: toggle task state
• Insert created time: insert a created time field into a task line
