What does EOD stand for? EOD stands for “end of day.” At work, it means a task should be done by the end of the current business day, usually around 5 p.m. in the sender’s time zone. Some people use EOD more loosely to mean any time before they check email the next morning.
What does EOD mean at work?
EOD is a same-day deadline. If a coworker asks, “Can you send it by EOD?” they want it today.
The exact time depends on who’s asking. In many offices, EOD means the end of normal working hours. For a manager who reviews files late at night, it may mean before midnight. Because of that, EOD is best for tasks where a few hours either way doesn’t matter.
You may also see:
- EOD today (by the end of today)
- EOD Friday (by the end of the day on Friday)
- EOD ET or EOD PT (with a time zone, for remote teams)
Outside offices, EOD can mean “explosive ordnance disposal” in the military. In work email, it always means end of day.
Examples of EOD in emails and messages
Email: “Please review the attached draft and send comments by EOD.”
Slack: “I’ll have the numbers to you EOD.”
Teams: “Running behind today, can I send it EOD tomorrow instead?”
Project tracker: “Status: on track. Final file EOD Thursday (6 p.m. ET).”
Client email: “We’ll send the updated quote by the end of the business day.”
EOD vs COB vs EOW
| Term | Stands for | Usually means |
|---|---|---|
| EOD | End of day | By the end of today, often 5 p.m. or sometimes before midnight |
| COB | Close of business | When office hours end, usually 5 p.m. local time |
| EOW | End of week | By the end of the last workday of the week |
| ASAP | As soon as possible | Right away, with no fixed time |
COB is a bit stricter than EOD because it’s tied to office hours. See COB and EOW.
How to use EOD correctly
- Add a time if it matters. “EOD (5 p.m. ET)” removes the guesswork.
- Name the time zone on remote teams. EOD in San Francisco is late evening in New York.
- Don’t send an “EOD” request at 4:45 p.m. Give people a realistic amount of time.
- Confirm if you’re receiving the deadline. “Is 6 p.m. okay, or do you need it before 5?”
- Say so early if you can’t make it. A heads-up at noon is better than a missed deadline at 5.
- Write it out for clients. “By the end of the business day” reads more professionally.
