perpetual_docket

1 = a standing/perpetual docket carrying a sentinel comment-end date (2050 or later; in practice 2099/2100 — agency guidance and exemption dockets that never close). 0 = an ordinary docket with a real deadline. NULL = no end date reported. The site's Open-for-Comment surface EXCLUDES perpetual_docket = 1 by default, so the site count and the bulk dump answer the same question differently: the dump is complete and includes them.

comment_end_date

The comment deadline as an Eastern (America/New_York) calendar date — CORRECTED in the 2026-09-06 daily snapshot (DataDawn queue #498): a snapshot whose _metadata row comment_end_date_grain reads 'eastern' carries the Eastern date; the pre-correction snapshots (through 2026-09-05) held the UTC-rolled day, one day LATE on every end-of-day close. Federal comment periods close at 11:59:59 PM Eastern and the source publishes that instant in UTC ('2026-08-26T03:59:59Z' = the 2026-08-25 deadline). Prefer comment_end_datetime for any arithmetic and convert it to America/New_York yourself; never 'subtract a day' from this column.

comment_end_datetime

AUTHORITATIVE. The full UTC instant of the comment deadline ('2026-08-26 03:59:59' == 11:59:59 PM Eastern on 2026-08-25). Convert to America/New_York for the official date; prefer this column over comment_end_date for anything computed.
