Reading Calendars

In this video, we’re going to learn how to use a calendar to tell the day and the month of an event and to write the date. We call this a calendar. This one’s made out of paper. But we can find calendars in all sorts of places, even on a mobile phone or a computer.

Calendars show all 12 months of the year. The first page of this calendar shows the first month of the year, which is January. Do you remember the 12 months of the year in order? January, February, March, April, May, June, July, August, September, October, November, and the last month of the year is December before we start back at January again in the new year.

So if we turn the page on our calendar from January, we get to see the month of February, then March, April, and so on. Let’s stop on the month of April. What can we see? We can see that part of the page has been divided into squares. We could call this a grid. And each of the squares has got a number in it, well, not all of the squares. Some of the squares have been shaded in with a color. These show us that they’re not part of the month of April. The only days in the month of April are those with numbers in them.

And the numbers tell us what day of the month it is. Here’s a question for you. How many days are in the month of April altogether? We can see that the first day of April has a number one written in it. This is the first day of the month. And the last day of the month is the one with the last number in it. We can see this is 30. So we can say there are 30 days in April altogether. The month of April begins on April the first, and it ends on April the 30th. When we write out a day of the year like this, we call it a date.

Now, what else can you see about our calendar? We can see that all the squares with numbers in, so that’s all the days of the month, are arranged in rows. How many squares are in each row? One, two, three, four, five, six, seven.

Now, why do you think the person that first designed the calendar decided to put seven squares in each row? Why not four or five or 10? There’s a reason why they chose seven. There’s a clue at the top of our calendar. Can you see the seven things that are written there? There are seven squares in each row because each square represents a different day of the week. There are seven days of the week, aren’t there? Now, we know what these letters refer to. Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday.

Now we can give even more information about the date. Let’s imagine that this girl has planned a trip to a museum. She’s so excited she’s put a big ring around the date on her calendar. And we ask her, when is it that you are going to the museum? Let’s read the date on the calendar to help her answer the question.

Our calendar shows us the names of the days of the week. And we can see that the number that the girl has circled is level with Saturday. We know the month of the year because it’s in big letters at the top of the calendar. And we can tell which day of the month it is by reading the number in the square. The girl can say she’s going to the museum on Saturday the 24th of April.

Let’s put into practice what we’ve learned now. We’re gonna try answering some questions where we have to read information from calendars.

Let’s take a look at the calendar. What month is it? What day is the first of the month? What day is the last of the month?

We can see a picture of one page of a calendar. Calendars are what we use to tell the time. Not what time of the day it is in hours and minutes. We use clocks and watches for things like that. But this tells us what time of the year it is, in months and days. And if we were to flip over this page of the calendar, we’d find a new month underneath.

Our first question has got the word “month” in it. What month is it? If we look carefully at the page of the calendar that we’re shown, we can only see one month on there. Can you find where it is? It’s here, isn’t it? We can see that the month of the year that the calendar shows is November. If you know your months of the year, you’ll know this is the month before the last month of the year.

Our second question has got a different time word in it. It asks us for a day. What day is the first of the month? We can see that the calendar is split up into lots of little rectangles. And most of them have got numbers in. These numbers are a way of showing us all the different days in November. So where do you think the first day of November will be?

The first day of November is shown by a rectangle with the number one in it. It’s November the first. Now, our question asks us, what day is the first of the month? In other words, what day of the week? If we look carefully at the top, we can see the days of the week if we go across the calendar. And if we put our finger on the first and move it upwards, we can see it’s level with this day of the week here.

Now, unfortunately, that blue ring we drew is covering over some of the word. But we can see that Wednesday is the day before it. So we can use our brains and think to ourselves what the day might be. The day after Wednesday is Thursday. On this calendar, the first day of November, which is November the first, happens on a Thursday.

Finally, we’ve got another “what day” question to answer. What day is the last of the month? To find the answer, we can use exactly the same skills as we used when we found the first day of the month. The last rectangle with a number in it is this one. So we know there must be 30 days in November. And if we put our finger on 30 and go all the way up to the top, we can see the day of the week. On this calendar, the last day of the month, which is the 30th of November, will happen on a Friday.

We’ve read our calendar to find out some facts. We know that the month of the year is November. The first day of November will be on a Thursday. And the last day of November will be on a Friday.

The Wednesday which follows the date shown will be the what of August.

In the picture, we can see an object which has the date written on it. Do you know the name for an object like this? It’s a calendar. But you might say, “Wait a minute! I thought a calendar was a page that showed a month on it and it showed all the different days of the month.” This calendar seems to just show one day, Sunday, August the 19th. What about the next day or the next day?

Well, the picture does show a calendar, but it’s a different sort of calendar than the one you might be used to. This one is a really thick calendar because it shows one day of the year at a time. We’re only shown one page of this calendar. So we need to try to think about what the rest of the calendar might look like, because the question asks us to think about days which follow the date shown. What do you think the next day after this day might look like?

Well, the day after Sunday will be Monday. There are 31 days in August. So the month isn’t going to change. It’s still going to be August. The day that follows the date shown will be Monday the 20th of August. If we read our question carefully, it doesn’t ask us for the day that follows the date shown. It asked us for the next Wednesday that follows the date shown.

You might be able to work the answer out in your head here. Or we could keep sketching calendar pages like this. But it’s always good to practice using the other sort of calendar. So let’s make a sketch of one of those.

First, we’ll start with the days of the week. We’ll start from Sunday because the day we’re looking at is a Sunday. We know all the days are in August, and the day we’re counting from is Sunday the 19th of August. So we don’t need to write all the other days from one to 18, we’re just starting from 19. This means that Monday will be the 20th of August. The Tuesday that follows the date shown will be the 21st of August. And the Wednesday that follows the date shown will be the 22nd of August.

We don’t need to do anything else. We don’t need to write all the numbers to the end of the month. We don’t even need to carry on to the end of the week. It’s only three days from Sunday to Wednesday, and that’s all we had to count on. The Wednesday which follows Sunday the 19th of August will be the 22nd of August.

If the 14th of November is a Monday, what day of the week is the 16th of November?

In this question, we’re given some information about a day of the year. And we need to use this to find some information about another day of the year. The day of the year we’re first told about is the 14th of November. And we’re told that this is a Monday. We need to use this information to help us find the day of the week that the 16th of November falls on.

Now, there are one or two ways we could find the answer to this. We could start on 14 and count on to 16, just see how many days that is. Another way to find the answer might be to think about what the calendar for November might look like. Let’s draw a quick sketch to help us. We know that calendars are split into rows of seven squares, one square for each day of the week.

Now, if we were sketching the whole month of November, we’d start with the number one. But our question talks about the 14th and then the 16th of November. So we only need to quickly sketch part of the calendar. We’re told that the 14th of November is a Monday, so we can write the number 14 in this square here. It’s level with Monday on our calendar. Now, let’s carry on writing some more numbers, and we’ve got the 14th, then the 15th, then the 16th. Do we need to carry on? We don’t, do we? We’ve got all the information we need.

If the 14th of November is a Monday, then the 15th of November must be the next day of the week, which is a Tuesday. And so the 16th of November must be a Wednesday. To get from 14 to 16, we count on two. And if we count on two days from Monday, we get to Wednesday. If the 14th of November is a Monday, the 16th of November will be on a Wednesday.

What have we learned in this video? We’ve learned how to use a calendar to tell the day and the month and to write the date.
