Q: If I’m told “火曜かよう日びまでに提出ていしゅつ,” should I submit it on Monday? Or is Tuesday still okay?

A: The expression “火曜かよう日びまでに提出ていしゅつ” means you can submit it anytime before the end of Tuesday.
In other words, Tuesday is included as a valid submission day.

〜までに

[Rule]
[V] Verb dictionary form + までに
[N] Noun (time/date) + までに

[Examples]
お母かあさんが帰かえってくるまでに、部屋へやを片付かたづけよう。
Let’s clean up the room before Mom comes home.

お客きゃく様さまが来くるまでに会議かいぎ室しつを掃除そうじしてください。
Please clean the meeting room before the guests arrive.

レポートは今週こんしゅうの火曜かよう日びまでに出だしてください。

5月がつ10日かの13時じまでに申もうし込こみしなければなりません。
You must apply by 1:00 p.m. on May 10th.

“までに” means “to do something before a certain time comes” and is used to indicate a deadline.

A “deadline” refers to a specific point in time, and that day is included as part of the deadline.
For example, if you are told “Submit it by Tuesday,” it means that submitting the item within business hours on Tuesday is acceptable.

However, depending on the reception hours of the receiving party, you may need to complete the action within their working time.
For instance, if a facility closes at 5:00 p.m., and you’re told “Return it by the 20th,” it means you should return it by 5:00 p.m. on the 20th.

[Examples]
この本ほんは20日かまでに返かえしてください。
Please return this book by the 20th.
⇒ The final due date is the 20th. If the facility closes at 5:00 p.m., return it by 5:00 p.m. on the 20th.　

こちらの申込もうしこみ書しょは日曜にちよう日びまでに、持もってきてください。 　　
Please bring this application form by Sunday.
⇒ The final due date is Sunday. If the shop closes at 8:00 p.m., bring it by 8:00 p.m. on Sunday.

[Note for Business Situations]
日本にほんでは、時間じかん厳守げんしゅだけでなく時間じかんに余裕よゆうを持もった行動こうどうが信頼しんらいにつながると考かんがえられています。
たとえば「12時じまでに来きてください」と言いわれたときに、ぴったり12時じに到着とうちゃくするのはギリギリすぎる印象いんしょうを与あたえることもあります。10〜15分ぶん前まえを目安めやすに行動こうどうすると安心あんしんです。

[Example]
この資料しりょう、明日あしたの13時じ頃ころまでに仕上しあげてくれる？
Can you finish this document by around 1:00 p.m. tomorrow?
⇒ In this case, it’s better to finish earlier than 1:00 p.m. If you submit it very close to the deadline, it’s polite to say something like “Sorry for the last-minute delivery.”

Q: How do you correctly use “1時間じかん弱じゃく” and “1時間じかん強きょう”?

A: “1時間じかん弱じゃく” means slightly less than one hour, while “1時間じかん強きょう” means slightly more than one hour.
For example, if something takes about 55 to 59 minutes, you can say “1時間じかん弱じゃく”; if it takes 1 hour and 1 to 5 minutes, you can say “1時間じかん強きょう”.

These expressions are not limited to time—they are also commonly used for other quantities such as weight or number of people (e.g., “2キロ弱じゃく” = just under 2 kilograms, “200人強きょう” = just over 200 people).
They are frequently used in both business and everyday conversations, so it’s useful to understand and use them correctly.

弱じゃく/強きょう

[Rule]
Quantity-related word + 弱じゃく／強きょう

[Examples]
会場かいじょうには2000人にん強きょうが集あつまりました。
More than 2,000 people gathered at the venue.

気温きおんが連日れんじつ38度ど強きょうもあって耐たえられないよ。

あそこまで歩あるいたら1時間じかん弱じゃくかかりますよ。
If you walk all the way over there, it will take just under an hour.

このかばんは1キロ弱じゃくありますね。
This bag weighs just under one kilogram.

“弱じゃく” (just under) means slightly less than the stated value,
and “強きょう” (just over) means slightly more than the stated value.

For example, “1時間じかん弱じゃく” refers to approximately 55 to 59 minutes,
and “1時間じかん強きょう” refers to 1 hour and 1 to 5 minutes.

These expressions are useful for conveying approximate amounts,
and can be applied to time, weight, number of people, distance, and other quantities.

[Examples]
体温たいおんを測はかったら37度ど強きょうありました。
When I took my temperature, it was a little over 37°C.
⇒ This means the temperature was above 37°C.

A「この荷物にもつは何なんキロですか。」
B「うーん、だいたい2キロ弱じゃくですね。」
A: “How much does this package weigh?”
B: “Hmm… It’s roughly just under 2 kilograms.”
