Weekday
Noun
ようび
水曜日は、ネイティブが話すスピードで日本語を話す日にしませんか？
Why don't we make Wednesday the day we try speaking Japanese at the speed of native speakers?
今日って何曜日だっけ？
What day of the week is today?
肝心なのは、この日本語の課題を金曜日までに終わらせなければならないということだ。
The bottom line is that we have to finish this Japanese assignment by Friday.
The weekday day is the day of the week, as in "Monday" or "Tuesday." You'll be learning those on level 18, but first you should learn 曜日 to get you prepared.
This word uses the on'yomi reading for 曜 and the kun'yomi reading for 日. You've learned both of these already, but be careful because ひ of 日 changes to び here.
