How Early Should You Arrive for a "9:00 Meetup"? How to Tell Someone You'll Be Late

"Meet at 9:00" can mean arriving at the building at 9:00, or it can mean being ready to start at 9:00. Which one it means depends on the company, school, or gathering. It is fine to ask when you are not sure. If you realize you will be late, get in touch before you arrive.

*This scene is fictional, based on situations that are common among learners.

Camila arrived in front of a training venue she had never been to before, at exactly 9:00. She sent a message on her smartphone to Mr. Kono, the person in charge: "I've just arrived."

After that, she waited for the elevator, wrote her name at the reception desk, and opened the door of the room she was directed to at 9:08. Self-introductions had already begun inside. Mr. Kono said, "We had planned to start at 9:00."

Camila had thought she was not late because she had arrived at 9:00. Mr. Kono had expected her to be seated in the room by 9:00.

What "9:00" Refers To Changes by Situation

The time you reach the entrance of a building and the time you can start in your seat in the room are not the same. In a building you have never been to, reception and getting around take longer than you might expect.

When you arrange to meet a friend by saying "10:00 at the station," the promise is to be at that place at 10:00. At work or in training, people sometimes say "meet at 9:00" to mean "we start at 9:00." The rules differ from one workplace to another. It is reassuring to ask in advance.

• "I understand we're meeting at 9:00. Should I arrive so that we can start at 9:00?"
• "I imagine there will be a reception desk on the day. About how many minutes before should I arrive?"

Online meetings are the same. If you join a little early and check your audio and screen so that you can start speaking at the start time, you will have time to fix things if something goes wrong. How many minutes early depends on the meeting. If the notice says so, follow it.

When You're Told to Come Early, You Can Ask How the Time Is Treated

At shops, factories, and similar places, you may be told to come early to allow time to change into a uniform. Does this preparation time count as working time?

The guidelines of the Ministry of Health, Labour and Welfare list, as an example of time that must be treated as working time, time spent on preparatory activities carried out within the workplace at the employer's instruction. An example of a preparatory activity is "changing into the prescribed clothing that one is required to wear" [1]. Whether something is working time is not decided by the terms of a contract or work rules; it is judged case by case, based on factors such as whether the activity was obligatory [1].

The Supreme Court has also held that, when a worker was required to perform a preparatory activity within the workplace, or had no choice but to do so, the worker can be regarded as being under the employer's direction and control, unless there are special circumstances. The time that activity required counts as working time to the extent that it is recognized as necessary under common social standards [2].

So when someone says, "Please come early to change clothes," you are free to ask whether this is the company's instruction or something expected of you as a matter of personal attitude.

• "Do I need to arrive before 9:00 in order to change?"
• "Does that time count as working hours?"

If You Know You'll Be Late, Contact Them Before You Arrive

An explanation of how to notify a part-time workplace about lateness recommends contacting them as soon as you know you may be late, rather than putting it off [3]. The things to convey are three: the reason, the time you can arrive, and an apology [3]. After receiving your message, the other person can decide whether to wait or to start without you.

• When your train is delayed: "My train is delayed, so I expect to arrive around 9:10. I'm sorry."
• When you get lost in a building you've never been to: "I can't find the entrance, so it looks like it will be around 9:05. I'm sorry."
• For an online meeting: "I'm having trouble connecting, so I'll join about two minutes late. I'm sorry."
• When you can't tell when you'll arrive: "The train has stopped, so I won't make it by 9:00. I'll contact you again once I know when I'll arrive."

The basic way to contact them is by phone. If you can't call, such as when you're on a train, LINE or email is fine. If you don't get a reply soon after sending, call them [3].

Bad news is better shared early, and this is not true only of lateness. If they learn early, the other person can change their next preparations.

"I Contacted You, So Being Late Is Okay, Right?"

Even if you get in touch, the lateness does not disappear. Contacting them is meant to let the other person make a plan for how long they will have to wait.

With your message, the other person can know "what time you'll come." Even so, the fact that they were kept waiting does not change. If you keep being late with the attitude of "I contacted them, so it's fine," people are likely to think, "Late again?" When lateness continues, it is more useful to change the time you leave home or the train you take than to rely on contacting them.
