TBD means “to be determined.” In a text, it tells you that a detail such as a time, place, or decision has not been settled yet and will be confirmed later. “Dinner is Friday, restaurant TBD” is a typical example.
The abbreviation is common in texts, calendar invites, schedules, and job ads. It also has a few lookalikes and rarer meanings, and it is often confused with TBA and TBC. This guide covers what TBD means, how it reads in different settings, and how to reply.
What Does “TBD” Mean in Text?
TBD is shorthand for “to be determined,” and some sources also list “to be decided.” Dictionary.com, Oxford Learner’s Dictionaries, and the Britannica Dictionary all define it that way, and the Britannica entry describes it as a note that a time or place has not yet been decided.
It is not new slang. Wikipedia notes that a reference work reported TBD as early as 1967. In chats, it works as a placeholder: the plan exists, but one piece is still open.
What does TBD mean in time
When TBD follows a time, as in “meeting at TBD,” the time has not been chosen. Nobody has promised a start yet, so do not plan around it.
Sometimes the text gives a follow-up, such as “time TBD, will confirm Thursday.” That is more useful, because it names a date for the decision. If it does not, a quick “When will we know?” helps.
The Most Common Meanings of “TBD”
The core meaning stays the same, but the thing being left open changes with the setting.
| Setting | What TBD Usually Means | Example |
|---|---|---|
| Text with friends | A plan detail is undecided | “Movie night is Saturday, movie TBD.” |
| Calendar invite | Time or location not set | “Team lunch, location TBD.” |
| Job ad or project tracker | A date or owner is not set | “Start date: TBD.” |
| Sports schedule | Game time or opponent not set | “Week 12, at home, TBD.” |
| Unrelated names | A brand or title, not a message | The TBD television network |
TBD meaning in football
In football and other sports, TBD appears in schedules when a game time, opponent, or venue has not been set. Dictionary.com’s examples include a Los Angeles Times season preview that lists a Chargers game with TBD in place of a detail.
It also shows up in availability notes, such as a basketball player listed as TBD for the second game of a back-to-back. It means “we will know later,” not “out” or “in.”
How “TBD” Is Used in Real Conversations
- Making plans: “Are we meeting at 6?” “Time is TBD, waiting on Sam.”
- Work chat: “Deadline TBD until the client replies.”
- Events: “The party is next week, venue TBD.”
- Short reply: “Not sure yet, TBD.”
TBD meaning in relationship
There is no documented relationship-specific definition of TBD. It keeps its ordinary meaning, and in dating talk it usually signals that the status or the plan is undecided. For example, answering “what are we?” with “TBD” means the person has not decided.
That can feel noncommittal, so do not read it as a yes or a no. If the answer matters to you, ask directly what they are deciding and when they expect to know.
Is “TBD” Rude, Flirty, or Offensive?
TBD is neutral. It has no flirty or offensive meaning, and most people read it as plain scheduling language.
Tone can still matter. A bare “TBD” in reply to a direct question can sound dismissive, especially in a personal conversation. Adding a reason or a follow-up date, such as “TBD, I’ll let you know tonight,” keeps it friendly.

TBD country
I found no country called TBD and no official country code with those letters. When you see “country: TBD” on a form or list, it means the country has not been chosen or entered.
One lookalike exists: TBD is the IATA airport code for Timbiqui Airport in Cauca, Colombia, according to Wikipedia. In a travel context, it could refer to that airport, but the surrounding words will make that clear.
How to Respond When Someone Says “TBD”
- Ask for a deadline: “When will you know?”
- Offer to help decide: “Want me to look at options?”
- Stay flexible: “Okay, keep me posted.”
- Check in later: “Any update on the time?”
What does TBD mean medical
I found no separate medical abbreviation for TBD. In a health setting, it keeps the ordinary meaning, as in “diagnosis TBD, awaiting test results.”
The letters do name a chemical compound, triazabicyclodecene, which appears in chemistry and not in everyday health messages. If you see TBD in your own medical paperwork, ask the office what is still undecided instead of guessing.
Common Misunderstandings About “TBD”
- It does not mean the event is canceled. It means a detail is open.
- It is not always a polite brush-off, although it can sound like one without context.
- It is not the same as TBA, which can mean details exist but are not public yet.
- It is not only for texting. It appears in contracts, schedules, and spreadsheets.
- Rarer meanings exist, such as the old term “torpedo boat destroyer,” but they do not appear in modern chats.
TBD meaning in school
In school, TBD marks schedules, assignments, or grades that are not final. A syllabus might list a project date as TBD, and a gradebook might show TBD where a result has not been entered yet.
It tells you to check back, not to worry. If a date matters, ask the teacher when it will be set.
Similar Slang Terms You Should Know
These placeholders look alike, but they do not mean the same thing.
| Term | Stands For | How It Differs |
|---|---|---|
| TBD | To be determined | The decision has not been made |
| TBA | To be announced | Details may exist but are not public |
| TBC | To be confirmed | A detail is set but could change |
| TBR | To be resolved | An issue is waiting for a fix |
| TBF | To be fair | An unrelated chat phrase with a similar look |
When You Should Avoid Using “TBD”
- When you already know the answer. Share it instead.
- In urgent plans, where an open detail leaves people stuck.
- With people unfamiliar with abbreviations, such as older relatives or clients, where “to be determined” is clearer.
- In a reply to a direct question when you can give a date for the decision.
TBD meaning in exam
For exams, TBD usually appears on timetables, seating notices, or result sheets. It can mean the exam date, room, or score has not been set. Because exam details affect your plans, check the official notice or ask the school for the confirmed information.
Final Thoughts
TBD is useful when it is honest and specific. The best messages say what is open and when it will be settled, such as “Venue TBD, I’ll confirm by Thursday.” That keeps people informed without creating confusion.
