In this grammar refresh, we'll be talking about how to use the preposition on and in when talking about
dates and days or months and years.
So when we use on it will be using this preposition with dates and dates, when we say dates really
mean that the actual number of the date.
Right.
So we use on these types of things dates or dates and of shorter periods of time, so we're arriving
on the 8th of April.
And again, the 8th of April, that's the British date format, if it was American, you'd say we're
arriving on April 8th.
Still both ways we use on it.
So another example is I don't work on Fridays.
Again, this is a date.
Don't work on Fridays.
So Friday is a day in April 8th.
That is also a date.
Right.
So, again, these are very similar.
Ellen is often grumpy on Monday mornings, again on and then the day.
The last example, we usually hang out at our place on Thursday night.
So even though we're talking about either Thursday night or Monday morning, right.
It's a part of the day.
This is a shorter period of time.
And we're using this preposition on.
And now, in contrast, when we have a longer period of time, like a month or a season or even a year.
We're going to use in the preposition in.
Kyle and Deborah are getting married in December.
It's not on December, it's in December.
Again, on is four days on Friday, on the 8th of April.
You could say island.
We are getting married on Friday, but Kyle and Debra are getting married in December.
The next example, it gets unbearably hot here in summer.
Again, it's not on summer, it's in summer is longer periods use in.
Our next example, our uncle was born in nineteen seventy three.
And the last example, the movie is set in the 80s.
