Federal comment dates for National Science Foundation

How the dates were read

Follow the notice before filing

This calendar reads dated events in the Federal Register’s DATES notes. The snapshot includes future dates found in the Register’s date query and a review of notices published in the prior 120 days. It was checked on November 10, 2026.

• Initial comments, replies, hearings, and requests for hearings appear separately when the notice supplies distinct dates. Some notices need a separate deadline calculation or an agency portal, so coverage varies.
• We link changed deadlines when an explicit revision matches an earlier notice by docket, agency and subject. The comparison pairs the same phase and counts calendar days between the two dates.
• Calendar files include an exact time when the note identifies a recognizable time zone. Other entries carry the printed date as an all-day reminder. Follow the notice for any filing instructions and later changes.
