In Japanese, there are a variety of words to express periods of time. Let's learn to use appropriate expressions according to the length of time you want to convey.

. ~日間(nichi kan)

The phrase “~日間” (nichi kan) means days. For example, “2日間” (futsuka kan) means two days. When the specific number of days is undecided, but you want to convey a certain period of time, you can say “数日間” (sūjitsu kan). Note, however, that “数日間” (sūjitsu kan) can be imagined differently from person to person.

Example

私は2日間入院しました。

Watashi wa futsuka kan nyūin shimashita.

I was hospitalized for 2 days.

Example

体調を崩してしまい、数日間会社を休んだ。

Taichō wo kuzushite shimai, sūjitsu kan kaisha wo yasunda.

I got sick and took a few days off from work.

When you want to ask someone, "How many days are you going to travel?”, you can say “何日間” (nannichi kan).

Example

あなたは何日間大阪に滞在する予定ですか?

Anata wa nannichi kan Ōsaka ni taizai suru yotei desuka?

How many days do you plan to stay in Osaka?

2. 半日(han'nichi)

The word “半日” (han'nichi) means half a day. In general, it means half the time between sunrise and sunset. Half of the working day is also sometimes referred to as “半日” (han'nichi).

Kyō wa han'nichi kinmu desu.

I work half a day today.

Example

健康診断に半日かかりました。

Kenkōshindan ni han'nichi kakarimashita.

3. 1日中(ichinichi jhū)

The term “1日中” (ichinichi jhū) means a whole day. It can also be described as ”朝から晩まで” (asa kara ban made) or “終日” (shūjitsu).

Example

The phrase “~ヶ月間” (kagetsu kan) means the period of months. The usage is the same as “~日間” (nichi kan). For example, “2ヶ月間” (ni kagetsu kan) means two months. In addition to “~ヶ月間” (kagetsu kan), it is written as “~ヵ月間,” “~か月間,” and “~箇月間,” but they all have the same meaning and pronunciation.

9. 半期(hanki)

The term “半期” (hanki) refers to the half of a year. It is similar to “半年”(hantoshi) but is often used for business. When a year is divided in half, the first half is described as “上半期” (kamihanki) and the second half as “下半期” (simohanki). The term “四半期” (shihanki) refers to the period in which a year is divided into four equal parts. All of these expressions are used in business. Companies close their accounts and make earnings forecasts within a year.

Example

もうすぐ1学期の終業式ですね。

Mōsugu ichi gakki no shūgyō-shiki desu ne.

The word “新学期” (shin gakki) is a combination of the kanji character “” (shin) meaning “new.” The term “新学期” (shin gakki) refers to a new semester starting.

Kyō kara shin gakki ga hajimarimasu.
