What it does
Resolve "lastYear" to a concrete ISO date range relative to your run time, the previous full calendar year. Returns inclusive civil dates plus exact UTC instants so you have temporal context without computing dates by hand. Read-only: no writes, no network. Use before a task over last year (annual reports, year-over-year).
/lastYear
Get the concrete date range for the previous full calendar year by running the bundled resolver:
node "$AGENT_DIR/.claude/skills/temporal/when.mjs" lastYear
It prints a human-readable line plus a JSON record:
start/end, inclusive civil dates (YYYY-MM-DD) in your local timezonestartUtc/endExclusiveUtc, the same window as a half-open[start, end)range of exact UTC instants, for timestamp-based queriesdays,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.
