GitHub

将“去年”解析为具体的ISO日期范围，提供本地时区日期和精确UTC时间戳。作为时间边界查询的唯一事实来源，避免手动计算日期，适用于年度报告等需要全年数据上下文的场景。

/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 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.
