Days of the Week - げつ or げつようび

[ByTheWay]

I wonder if someone could help with a passage from the Japanese for Busy People Textbook.

Here is the passage:

クラスは　いつ　あるんですか。

毎週　２回　月、金の　６時からです。　こんどの　き んようびに　いっしょに　行ってみませんか。


My question is: why is 月 and 金 used here instead of 月曜日 and 金曜日?



Thanks for looking at my question.

For the same reason that we'll write 'Mon-Fri' instead of 'Monday-Friday'. It's a shorthand for the days of the week that I tend to see most often in schedules or when dates for something are given in advance: i.e. 1/26/09 (火）.

Thanks for the reply, perhaps I can use this shorthand in the future when I write in Japanese.

You'll often see class schedules written something like this: 月水金, which is read げっすいきん.

Is that a special reading of 月? If so, are there any other exceptions I should know about?

Sometimes readings that end in a つ, in this case 月, change the last つ to a っ when used in compounds (So long as they aren't the last kanji of course)
I'm not sure if there is a rule to this.
I don't know if there is a name for it so I have never really been able to look it up, that's why I just learn them as they come up.

Another example is 発見【はっけん】
発【はつ】
見【けん】

But if we look at 発 in 発売 for example it is read はつばい

Thanks. Since none of the other kanji used in the days of the week have a reading ending in つ I suppose that means 月曜日 is the only exception.

Actually the exceptions don't relate only to つ. Think at the word for Japan made with the carachters 日(にち)and 本(ほん) read a にっぽん.
I had a list of all these exceptions in one of my text books...if I find it I print it here.

[yuriyuri]

That's a very good point chryuop, I guess in my experience I have mainly noticed the ones with つ in the word.
And if you do find that list it would be interesting to see them

[SceptileMaster]

In my book it lists a lot of those as readings though. I learnt にっ as a reading for 日.
