You’ve probably seen both “past due” and “Overdue” online, in emails, or on bills—and wondered which one is correct. You’re not alone. Thousands of people search this keyword every month because the two phrases sound similar but mean very different things. One is correct English. The other is a common mistake.
This confusion often appears in serious places: payment reminders, legal notices, business emails, and school assignments. Using the wrong version can make writing look unprofessional or even confusing. That’s why people search “past due or Overdue”—they want a fast, clear answer and confidence they’re using the right phrase.
This article solves that confusion once and for all. You’ll get a quick answer, the history behind the phrase, spelling differences between British and American English, real-world examples, common mistakes to avoid, and professional usage advice. By the end, you’ll know exactly which spelling to use—and when—without second-guessing.
Past the Due Date or Passed the Due Date
“Past the due date” is correct. “Passed the due date” is usually incorrect in formal English.
The phrase past the due date means something has gone beyond its deadline. It describes time, not action. For example: “The assignment is past the due date.” This usage is clear, correct, and widely accepted in both British and American English.
Passed the due date sounds similar but changes the grammar. The word passed is a verb and suggests an action. While native speakers may say it casually in speech, it is not recommended in professional or written English.
Correct example:
- The payment is past the due date.
Incorrect example:
- ❌ The payment is passed the due date.
For emails, invoices, reports, and formal writing, always choose past the due date.
Past Due or Passed Due – Quick Answer
“Past due” is correct. “Overdue” is incorrect in standard English.
Past due means something is late or overdue.
Overdue is grammatically wrong in this context.
Correct examples:
- The bill is past due.
- Your payment is past due by five days.
Incorrect example:
- ❌ The bill is Overdue.
If you’re talking about deadlines, payments, or time limits, past due is the only correct choice.
The Origin of Past Due
The phrase past due comes from the word “past,” meaning beyond a point in time. The word “due” means expected or scheduled. Together, past due literally means beyond the expected time.
This phrase has been used in English for centuries, especially in finance, law, and trade. It became common as written contracts and billing systems developed.
The confusion happens because “passed” is a verb (the past tense of pass), while “past” is usually an adjective or preposition. Since they sound the same, many writers assume Overdue must be right—but it isn’t.
