SEC Holidays & SEC EDGAR Filing Calendar

SEC Open Hours & EDGAR Submission Window

Outside of federal SEC holidays, the EDGAR system follows standard operating hours.

Typical SEC open hours for EDGAR filings:

  • EDGAR availability: Monday–Friday, 6:00 a.m. to 10:00 p.m. Eastern Time, excluding SEC holidays
  • Same‑day filing date cutoff:
    • Most filings must be accepted by 5:30 p.m. Eastern Time to receive that day’s filing date
    • Certain Section 16 filings (Forms 3, 4, and 5) can receive same‑day dates later in the filing window
  • Weekends & holidays:
    • If a due date falls on a Saturday, Sunday, or SEC holiday, the effective EDGAR deadline is the next SEC business day

Planning around these SEC open hours is especially important near quarter‑end and year‑end, when filing volume is highest and EDGAR tends to be busiest in the final hour of the filing day.

Other EDGAR Deadlines, Key Dates, and Compliance Planning

SEC filing requirements don’t stop at holidays. Public companies must also manage:

  • Form 10‑K, 10‑Q, and 20‑F deadlines based on filer status
  • Form 12b-25 NT 10‑K and NT 10‑Q notices and associated “late” filing windows
  • Ownership and Section 16 insider reporting deadlines on Forms 3, 4, and 5
  • Schedule 13D/13G, Form 13F, Form 144 and other ownership‑related filings and deadlines
  • Financial statement “staleness” dates for registration statements and proxy materials

When EDGAR Is Open, but U.S. Stock Markets Are Closed

Not every “day off” in the markets lines up with a SEC holiday. There are a few important distinctions:

  1. Days when the SEC is open but U.S. stock markets are closed
  2. Days when the SEC is closed but the stock markets are open

Both scenarios can affect how you plan EDGAR filings and investor communications

1. SEC Open, Markets Closed (Good Friday Example)

The SEC and EDGAR remain open on Good Friday, even though the NYSE and Nasdaq are typically closed. In 2026:

Date Day SEC Status U.S. Stock Markets Notes
April 3 Friday Open Closed (Good Friday) EDGAR accepts filings as usual

On this date:

  • EDGAR is available during normal SEC open hours
  • Filings submitted by the usual cutoff still receive an April 3, 2026 filing date
  • Trading is closed, but disclosure deadlines and internal reporting schedules may still apply

This can create a useful “quiet” day to catch up on filings—just be sure investor‑relations and legal teams are aligned on the optics of issuing material disclosures when markets are closed.

2. SEC Closed, Stock Markets Open (Columbus Day & Veterans Day)

The reverse is also true on some federal SEC holidays where stock markets typically remain open, but the SEC is closed, and EDGAR does not accept filings. In 2026:

DateDaySEC StatusU.S. Stock MarketsNotes
October 12MondayClosedOpenColumbus Day – EDGAR fully closed
November 11WednesdayClosedOpenVeterans Day – EDGAR fully closed

For these days:

  • No new SEC filings can be made through EDGAR
  • Any form with a deadline that would otherwise fall on these dates will generally be due the next SEC business day
  • Stock market‑moving disclosures may need to be timed carefully around both the SEC closed schedule and active trading hours

Coordinating disclosure timing around these mismatches (SEC calendar vs. market calendar) helps avoid last‑minute surprises and ensures compliance with both regulatory and market expectations.
