  a rolling 30-day window ending today. Returns inclusive civil dates plus exact UTC instants so you have

/last30Days

Get the concrete date range for **a rolling 30-day window ending today** by running the bundled resolver:

node "$AGENT_DIR/.claude/skills/temporal/when.mjs" last30Days

It prints a human-readable line plus a JSON record:

  • `start` / `end` — inclusive civil dates (`YYYY-MM-DD`) in your local timezone
  • `startUtc` / `endExclusiveUtc` — the same window as a half-open `[start, end)`

range of exact UTC instants, for timestamp-based queries

  • `days`, `timezone`, `asOf` — the span, your timezone, and when this resolved

Use the returned dates as the time bounds for the task at hand. **Do not derive dates by hand** — this resolver is the source of truth. For the full window list or an arbitrary range (e.g. `last45days`, `last6months`), see the `/temporal` skill.
