00:00:01,199 --> 00:00:04,940
Hello everybody, today we are going to talk about time prepositions.

2
00:00:05,559 --> 00:00:11,199
Okay, we are going to talk about three main time prepositions that are

3
00:00:11,199 --> 00:00:16,219
at, on, and in.

4
00:00:17,019 --> 00:00:20,420
We are going to start with the uses of at.

5
00:00:21,300 --> 00:00:25,980
So the first use of at is with a specific time.

6
00:00:26,760 --> 00:00:27,679
Let's see an example.

7
00:00:27,679 --> 00:00:29,839
She arrived at 9 o'clock.

8
00:00:29,839 --> 00:00:33,240
They finish school at 2 o'clock

9
00:00:33,240 --> 00:00:35,920
Or the movie starts at dinner time

10
00:00:35,920 --> 00:00:42,759
Okay, so 9 o'clock, 2 o'clock or dinner time are specific times

11
00:00:42,759 --> 00:00:45,579
Okay, specific moment

12
00:00:45,579 --> 00:00:51,679
So the preposition that goes before that is always at

13
00:00:51,679 --> 00:00:57,340
The second use of at is with a holiday period

14
00:00:57,340 --> 00:01:05,219
For example, they sing carols at Christmas or it's much fun hunting eggs at Easter.

15
00:01:06,079 --> 00:01:08,700
Christmas and Easter are holiday periods.

16
00:01:09,299 --> 00:01:16,340
It's not a day only, it's a period, a number of days that is that holiday period.

17
00:01:17,400 --> 00:01:17,540
Okay?

18
00:01:18,959 --> 00:01:21,359
Now we go to the uses of on.

19
00:01:21,540 --> 00:01:24,200
The first use of on is with days of the week.

20
00:01:24,200 --> 00:01:32,040
for example they will go back to school on monday or i visit my grandma on saturdays

21
00:01:32,599 --> 00:01:40,379
okay monday saturdays days of the week so the preposition that goes with it is on

22
00:01:40,379 --> 00:01:49,859
and then the other use of on or the other or when we use on is with dates example

23
00:01:49,859 --> 00:02:00,719
For example, on October 22nd I'm going to Cuba, on Christmas Day we have lunch with all the family, and my birthday is on the 5th of June.

24
00:02:01,840 --> 00:02:05,319
Notice in these examples, Christmas Day.

25
00:02:07,079 --> 00:02:19,699
So the difference between using at or on with Christmas, as we see, is that in the previous one, when we used at, we referred to a period.

26
00:02:19,860 --> 00:02:24,939
not to an specific day of Christmas, okay?

27
00:02:25,280 --> 00:02:31,479
In this case, we use on because we are referring to a specific day of Christmas,

28
00:02:31,719 --> 00:02:32,840
so it's a date.

29
00:02:33,439 --> 00:02:35,020
That's why we use on.

30
00:02:35,800 --> 00:02:37,879
And now let's see the uses of in.

31
00:02:38,800 --> 00:02:41,780
The first use of in is for months.

32
00:02:41,780 --> 00:02:48,020
So remember, on, for days of the week, in, for months of the year.

33
00:02:48,020 --> 00:03:00,159
school finishes in June her birthday is in August okay we also use in with years

34
00:03:00,159 --> 00:03:06,699
okay so we would say we will say he started working for the company in 1999

35
00:03:06,699 --> 00:03:17,620
Shakespeare was born in 1564 we also use it for decades so we have in plus the

36
00:03:17,620 --> 00:03:29,340
decade example life was different in the 80s i was born in the 70s okay so of course 80s so

37
00:03:29,340 --> 00:03:39,400
or 70s also for centuries in plus the plus century we are living in the 21st century

38
00:03:39,400 --> 00:03:43,639
or it was destroyed in the 19th century.

39
00:03:44,900 --> 00:03:49,900
Also for seasons, the time preposition that we use is in.

40
00:03:51,479 --> 00:03:53,560
They go skiing in winter.

41
00:03:54,580 --> 00:03:56,460
She was born in summer.

42
00:03:56,460 --> 00:04:03,590
And finally, with a time period.

43
00:04:04,569 --> 00:04:07,229
Example, the class finishes in 30 minutes.

44
00:04:07,810 --> 00:04:10,469
The play starts in 4 hours.

45
00:04:11,349 --> 00:04:14,229
Notice again the difference because we had at.

46
00:04:14,229 --> 00:04:24,189
So if I say the class begins at 9 o'clock, I'm talking about a specific time.

47
00:04:24,689 --> 00:04:24,850
No?

48
00:04:25,230 --> 00:04:26,870
So therefore I used at.

49
00:04:27,269 --> 00:04:35,930
Here we are talking about a time period, 30 minutes or 4 hours.

50
00:04:35,930 --> 00:04:40,850
so we use in because it refers to all that time

51
00:04:40,850 --> 00:04:46,730
all those 30 minutes or the whole 4 hours

52
00:04:46,730 --> 00:04:51,930
ok, and well, that's all about time prepositions

53
00:04:51,930 --> 00:04:53,990
I hope you understood

54
00:04:53,990 --> 00:04:59,089
and now of course you can go and do some exercises

55
00:04:59,089 --> 00:04:59,889
bye bye
