What does the abbreviation EOD stand for?

According to Hubspot, the term EOD stands for end of day. This is usually used as a deadline to refer to the end of the business day. This is similar to the terms COB, EOP and COP, which stand for close of business, end of play, and close of play. People will often use EOD and other similar acronyms with a colleague to ask for something by the end of different business days so it is ready for the next morning. Sometimes this can cause confusion depending on the different time zone – if the sender’s time zone is in Eastern Standard Time (EST) but the recipient is in Pacific Standard Time (PST), it is important to clarify which EOD they are referring to. Additionally, sometimes it is necessary to clarify if a person means end of business day or end of the day as in midnight. If someone is waiting on something for close of business on Friday to have it ready for Monday but it isn’t completed until midnight Friday, this may cause frustration. 

COB, or close of business, is usually used to refer to the close of the financial markets in the specific time zone EST as that is the end of the trading day in New York City. At this time, trading stops and it is therefore referred to as close of business. 

According to The Free Dictionary, EOD has many other potential different meanings. These similar acronyms are still valid, but are used less frequently.
