From Chat GPT:
The EDGAR system is open until 10 p.m. Eastern Time today for submitting filings, except on federal holidays. However, for most types of filings, the same-day filing deadline is 5:30 p.m. ET, meaning submissions made after that time will receive the next business day's filing date. There are exceptions for certain submissions, such as Section 16 and MEF filings, which can be submitted up until 10 p.m. ET and still receive the current day's filing date.
