00:00:11,570 --> 00:00:17,829
Good morning kids, I'm Patri and let's go to start the class.

2
00:00:17,829 --> 00:00:21,289
We talk about the past in number of years.

3
00:00:21,289 --> 00:00:31,190
A year is 365 days or 12 months.

4
00:00:31,190 --> 00:00:33,189
Every year has a number.

5
00:00:33,189 --> 00:00:38,409
The year 1 is the year when Jesus Christ was born.

6
00:00:38,409 --> 00:00:43,070
We count the rest of the years starting from this point.

7
00:00:43,710 --> 00:01:02,859
When we say years, we separate them like this, 7-11, 12-12, 2015, 4-01, 17-05, but sometimes

8
00:01:02,859 --> 00:01:17,200
we don't do this in 50 800 1000 1500 1800 and 2005 in history we count years

9
00:01:17,200 --> 00:01:25,859
in hundreds 100 years is one century so the rule about years and centuries we

10
00:01:25,859 --> 00:01:30,379
are going to follow these steps put your finger on the last two numbers of the

11
00:01:30,379 --> 00:01:36,379
year. Add 1 to the rest of the numbers and if you don't have any number is 0.

12
00:01:36,379 --> 00:01:46,590
Years after the birth of Jesus Christ are called AD and years before the birth

13
00:01:46,590 --> 00:01:51,230
of Jesus Christ are called BC.
