Biweekly Or Semiweekly Meaning

November 16, 2025 services

English is full of words that can easily confuse even native speakers, especially when it comes to time-related terms. One such example is the use of biweekly and semiweekly. Both words are often used to describe the frequency of events or schedules, but they can carry different meanings depending on context. The lack of clarity between these terms can lead to misunderstandings in the workplace, education, finance, and everyday life. Understanding what each term means, and how to use it correctly, is key to effective communication.

Understanding the Term ‘Biweekly’

Definition of Biweekly

The word biweekly has two common meanings, which is the root of the confusion:

Occurring every two weeks (once every fourteen days).
Occurring twice a week (two times in one week).

In most modern American English usage, biweekly typically refers to something happening every two weeks. For example, if someone gets a biweekly paycheck, it usually means they are paid once every two weeks, not twice per week.

Examples of Biweekly in Sentences

We have a biweekly meeting on Mondays, so the next one is two weeks from now.
Employees are paid biweekly, resulting in 26 paychecks per year.

However, some sources and speakers may use biweekly to mean twice a week. Because of this, it’s always a good idea to ask for clarification if the intended meaning isn’t obvious.

Understanding the Term ‘Semiweekly’

Definition of Semiweekly

Semiweekly is less ambiguous and more specific. It always means twice a week or two times per week. This clarity makes semiweekly the better term when referring to something happening twice in one week.

Examples of Semiweekly in Sentences

The company releases semiweekly updates on Tuesday and Friday.
Our semiweekly training sessions help us stay sharp and consistent.

Unlike biweekly, the word semiweekly is rarely misunderstood, though it is less commonly used in everyday conversation. Still, in professional or technical writing, it is helpful to use semiweekly when you need to avoid confusion.

Why the Confusion Exists

Root of the Problem

The confusion comes from how English uses prefixes. The prefix bi- means two or every two, while semi- means half or twice. For example:

Biannual = every two years
Semiannual = twice per year

When applied to weeks, the same logic follows:

Biweekly = every two weeks (though sometimes used as twice a week)
Semiweekly = twice a week

Regional Differences

American English and British English may differ slightly in how they use and understand these terms. In the U.S., biweekly generally means every two weeks, while in the U.K., there may be more variation depending on context. This makes clarity even more important in global communication.

Biweekly or Semiweekly in the Workplace

Payroll and Schedules

In many jobs, employees are paid either weekly, biweekly, or monthly. Understanding the meaning of these terms is important for budgeting and financial planning.

Biweekly pay: Means a paycheck every two weeks. Most people receive 26 paychecks a year.
Semiweekly meetings: These would occur twice per week, perhaps on Mondays and Thursdays.

Incorrectly assuming the meaning could lead to missed deadlines, misunderstandings about compensation, or scheduling errors.

Communicating Clearly

To avoid misinterpretation, it’s often better to use plain language. Instead of saying biweekly, say every two weeks or twice a week if you want to be specific. For example:

Let’s meet every two weeks on Friday instead of Let’s meet biweekly.
We’ll update the report twice per week instead of We’ll do semiweekly reports.

Alternative Synonyms and Clarifiers

Other Ways to Say Biweekly or Semiweekly

When in doubt, consider using more specific phrases. These eliminate the ambiguity associated with the original terms.

Every two weeks
Once every fourteen days
Twice per week
Two times a week

These expressions are clear and understandable across different English-speaking regions and professional settings.

Biweekly vs Semiweekly: Which Should You Use?

Guidelines for Choosing the Right Term

Choosing between biweekly and semiweekly depends on the context and your audience. Here are some guidelines:

If you mean every two weeks, use biweekly or every two weeks.
If you mean twice a week, use semiweekly or twice per week.
When writing professionally, clarify in parentheses (e.g., biweekly (every two weeks)) to prevent confusion.

Avoiding Miscommunication

In both business and casual conversations, it’s better to be overly specific than to leave room for doubt. Especially when scheduling events or discussing recurring tasks, stating the exact days or frequency helps everyone stay on the same page.

Real-Life Scenarios

Using the Terms in Practice

Job Interviews: This position pays biweekly, with paydays every other Friday.
Fitness Coaching: Your semiweekly sessions are scheduled for Monday and Wednesday.
Team Meetings: Let’s switch from weekly to biweekly meetings to allow more time for progress between sessions.

Each example shows how understanding and correctly using these terms can improve communication in real scenarios.

Know the Difference and Use It Well

Understanding the difference between biweekly and semiweekly can help avoid misunderstandings in communication. While biweekly is commonly used to mean every two weeks, it sometimes is used to mean twice a week causing confusion. Semiweekly, on the other hand, specifically refers to events that happen twice a week. For the clearest communication, especially in professional or academic settings, it is best to use detailed phrases like every two weeks or twice per week. By being mindful of your audience and using unambiguous terms, you can ensure your message is always clear.
