Finds fair meeting times for distributed teams. Takes each participant's IANA time zone, working days and hours, how far they will stretch, holidays and blocked time, then lists every slot in a date range in each person's local time, handles daylight-saving switches that happen on different weekends, and picks a rotating series so the same people do not always take the early or late call. Includes a stdlib Python zoneinfo script with --self-test.
Compares two CSV exports of the same records (old vs new, billing vs ledger, source vs warehouse) by key after normalizing headers, delimiters, currency formats, accounting negatives, dates and case. Reports added, removed and duplicate keys, key format drift, changed values per column with tolerances, possible re-keys and a control-total bridge, then writes a reconciliation report. Includes a stdlib Python checker with --self-test.
