Due On, Due By, Or Due For? Difference Explained (+18 Examples)

Prepositions come after many words in English, and it’s important to understand how the meaning of words changes based on which preposition follows it. Let’s look at whether we use due on, due by, or due for, and what each one means.

What Is The Difference Between Due On, Due By, And Due For?

Due on should be used when something must be submitted on a given date and no other time. Due by should be used when something can be submitted on a given date or before. Due for should be used when something is submitted to a person, rather than a time.

When Is The Deadline Day Included?

When you want to announce the deadline day, it always comes after the preposition. That means you can say “due on Friday” or “due by Tuesday next week.”

You can only put the deadline day after the preposition to indicate the urgency of the submission to the people you’re talking to. “Due on Friday” shows the urgency of getting it completed by Friday, while “due by Friday” shows that you can do it by Friday or before.

Does Due By Friday Mean On Friday Or Before Friday?

“Due by Friday” means both on and before Friday. It’s up to you how you want to interpret the message. Usually, you will start to work on the submission early and see how long it takes you to complete.

When something is “due by Friday,” it means you have until Friday to complete it. If you work on it earlier than that and complete it before Friday, you can hand it in whenever it’s ready.

Usually, tasks that are “due by” aren’t as urgent as ones that are “due on,” and there’s no given time frame for how long that task might take somebody to complete. Some people like to leave “due by” tasks until the last minute and hand it in on the last day, but this isn’t always a wise decision.

Is Completing A Task On The Due Date Considered Overdue?

Depending on what was asked of you, completing a task on the due date may be considered overdue. Typically, you want to finish the task before the due date to make sure that you can hand it in on time, ready for the due date.

Due dates usually include a day and a time. If you decide to complete your task on the expected day, you may often be overdue, as many people choose to finish their tasks earlier in the week to make sure they have something to hand in.

Of course, the time you hand something in and the time you complete it depends on the task in question. Some school assignments might take less time than a data-entry assignment would at your workplace. It’s dependent on what someone asked you to do, just as much as it’s dependent on your own work ethic.

Generally, make sure you get your task completed before the due date. That way, you’ll never hand in work that’s overdue.
