What This Year does

This Year resolves the current calendar year up to today as an inclusive ISO date range and exact UTC instants. Use it before year-to-date tasks such as metrics or reports so temporal bounds are consistent without manual date calculation.

This Year is cataloged under Data on DirSkills. This Year comes from a repository tagged agents, claude-code, free, harness and harness-engineering.

From the original repository

/thisYear

Get the concrete date range for this year so far (Jan 1 → today) by running the bundled resolver:

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

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.
