Questions & Answers about shuurikanryouyoteibi wa kinyou desu.

What does 修理完了予定日 mean as a single chunk?

It is a compound noun made of smaller parts:

• 修理 = repair
• 完了 = completion
• 予定 = scheduled / planned
• 日 = day / date

So 修理完了予定日 means something like the scheduled date of repair completion or the expected completion date for the repair.

Japanese often stacks nouns together like this, much more than English does.

Why is は used after 修理完了予定日?

は marks the topic of the sentence.

So:

• 修理完了予定日 = the scheduled repair completion date
• は = as for...
• 金曜です = is Friday

A very natural English rendering is:

• The scheduled repair completion date is Friday.
• or As for the repair completion date, it is Friday.

Even though は is often introduced as meaning is or as for, it does not exactly equal any one English word. Its job is to show what the sentence is about.

Why is there no が here instead of は?
