Wk. is the short written form of weekWk.是week（星期／週）的書面縮寫。You will see it where space is tight and nobody wants to write the whole word你會在空間不夠、沒人想寫完整單字的地方看到它: a calendar square行事曆的一格, a timetable時間表, a work schedule工作排程, a note to yourself或自己寫的筆記裡。

"2 wks." means two weeks; "wk. 3" means week three of a course or a plan. It is writing only — when you read it out loud, you say the full word "week" or "weeks", never the letters.

"2 wks." means two weeks"2 wks."的意思是兩個星期; "wk. 3" means week three of a course or a plan"wk. 3"則是指一個課程或計畫的第三週。It is writing only這只用在書寫上 — when you read it out loud你唸出來的時候, you say the full word "week" or "weeks"要唸出完整的"week"或"weeks", never the letters絕不會唸字母。

Two things worth knowing. First, the dot at the end is what marks it as a shortening, and British writers often drop it and just write wk, while American writers tend to keep wk. — both are fine, and nobody will correct you.

Two things worth knowing有兩件事值得知道。First第一, the dot at the end is what marks it as a shortening結尾那個點就是標示這是縮寫的記號, and British writers often drop it and just write wk英式寫法常常會省略那個點，直接寫wk, while American writers tend to keep wk.美式寫法則習慣保留wk. — both are fine, and nobody will correct you兩種都可以，不會有人糾正你。

Second, wk. belongs to the informal, practical corner of writing. In a proper letter, an essay, or anything you hand to a teacher or a boss, write week out in full. Save the short form for your own notes and for forms and tables where the space really is small.

Second第二, wk. belongs to the informal, practical corner of writingwk.屬於書寫裡比較非正式、實用取向的那一塊。In a proper letter, an essay, or anything you hand to a teacher or a boss在正式的信件、文章，或任何要交給老師或老闆的東西裡, write week out in full請把week完整寫出來。Save the short form for your own notes and for forms and tables where the space really is small縮寫就留給自己的筆記，還有那些空間真的很小的表格使用。
