How To Get Week Number From Date In Power Bi?

**How to Get the Week Number from a Date in Power BI**

The week number is a useful metric for tracking data over time. It can be used to compare data between different weeks, or to identify trends over time. In Power BI, there are a few different ways to get the week number from a date.

In this article, we will show you three different ways to get the week number from a date in Power BI. We will also provide some tips on how to use the week number to analyze your data.

1. Using the WEEKNUM Function

The WEEKNUM function is the most straightforward way to get the week number from a date in Power BI. The syntax of the WEEKNUM function is:

“`
WEEKNUM(date, [first day of week])
“`

where `date` is the date you want to get the week number for, and `first day of week` is the day of the week that you want to use as the start of the week.

For example, the following formula will get the week number for the date `2023-01-01`:

“`
WEEKNUM(DATE(2023, 1, 1))
“`

The result of this formula will be 1, because January 1st is the first day of the week in the United States.

2. Using the DATEPART Function

The DATEPART function can also be used to get the week number from a date. The syntax of the DATEPART function is:

“`
DATEPART(interval, date)
“`

where `interval` is the interval you want to get, and `date` is the date you want to get the interval for.

To get the week number, you would use the following syntax:

“`
DATEPART(“week”, date)
“`

For example, the following formula will get the week number for the date `2023-01-01`:

“`
DATEPART(“week”, DATE(2023, 1, 1))
“`

The result of this formula will be 1, because January 1st is the first day of the week in the United States.

3. Using the CALCULATE Function

The CALCULATE function can also be used to get the week number from a date. The syntax of the CALCULATE function is:

“`
CALCULATE(expression, filter)
“`

where `expression` is the expression you want to calculate, and `filter` is the filter you want to apply.

To get the week number, you would use the following syntax:

“`
CALCULATE(WEEKNUM(date), date > DATE(2023, 1, 1))
“`

For example, the following formula will get the week number for all dates that are greater than or equal to January 1st, 2023:

“`
CALCULATE(WEEKNUM(date), date >= DATE(2023, 1, 1))
“`

The result of this formula will be a table of the week numbers for all dates that are greater than or equal to January 1st, 2023.

| Column 1 | Column 2 | Column 3 |
|—|—|—|
| Step 1 | Select the date column in your Power BI data table. | |
| Step 2 | Click the Date & Time tab in the ribbon. | |
| Step 3 | Click the Week Number button. | |
| Result | A new column will be added to your data table with the week number for each date. | |

In this tutorial, you will learn how to get the week number from a date in Power BI. You will learn about the different ways to get the week number, and you will see how to use the week number in your Power BI reports.

What is the Week Number?

The week number is a way of expressing the position of a date within a year. It is typically expressed as a number between 1 and 53, with 1 being the first week of the year and 53 being the last week of the year.

The week number can be calculated using a variety of methods, but the most common is to use the ISO 8601 week numbering system. The ISO 8601 week numbering system starts on a Monday and ends on a Sunday. The first week of the year is the week that contains the first Thursday of the year.

How to Get the Week Number in Power BI?

There are a few ways to get the week number in Power BI. The easiest way is to use the `WEEKNUM` function. The `WEEKNUM` function takes a date as its input and returns the week number for that date.

The following formula returns the week number for the date 2023-01-01:

“`
=WEEKNUM(DATE(2023, 1, 1))
“`

The `WEEKNUM` function can also be used to get the week number for a date range. The following formula returns the week numbers for the dates 2023-01-01 to 2023-01-07:

“`
=WEEKNUM(DATE(2023, 1, 1), DATE(2023, 1, 7))
“`

You can also use the `DATEPART` function to get the week number. The `DATEPART` function takes a date and a part as its inputs and returns the value of that part for that date. The `WEEK` part returns the week number for a date.

The following formula returns the week number for the date 2023-01-01:

“`
=DATEPART(“WEEK”, DATE(2023, 1, 1))
“`

The `DATEPART` function can also be used to get the week number for a date range. The following formula returns the week numbers for the dates 2023-01-01 to 2023-01-07:

“`
=DATEPART(“WEEK”, DATE(2023, 1, 1), DATE(2023, 1, 7))
“`

Using the Week Number in Your Power BI Reports

Once you have the week number, you can use it in your Power BI reports in a variety of ways. You can use the week number to filter data, group data, or create calculated columns.

For example, you could use the week number to filter data to show only the data for the current week. You could also use the week number to group data by week, so that you can see how the data has changed over time.

You could also use the week number to create calculated columns. For example, you could create a calculated column that calculates the total sales for each week.

How To Get Week Number From Date In Power BI?

In this tutorial, you will learn how to get the week number from a date in Power BI. You will learn two methods:

• Using the DateAdd function
• Using the WeekNum function

Using the DateAdd function

The DateAdd function adds a specified number of days, months, or years to a date. You can use the DateAdd function to get the week number from a date by adding 7 days to the date and then dividing the result by 7.

For example, the following formula will get the week number for the date 1/1/2023:

“`
=DATEADD(DATE(2023,1,1),7,DAY)/7
“`

The result of this formula will be 1, which is the week number for the week that starts on 1/1/2023.

Using the WeekNum function

The WeekNum function returns the week number for a date. The WeekNum function takes two arguments:

• The first argument is the date.
• The second argument is the first day of the week. The default value for the first day of the week is Sunday.

For example, the following formula will get the week number for the date 1/1/2023, with the first day of the week being Sunday:

“`
=WEEKNUM(DATE(2023,1,1))
“`

The result of this formula will be 1, which is the week number for the week that starts on 1/1/2023.

Examples of Using the Week Number in Power BI

The week number can be used to filter data. For example, you could use the week number to filter data to show only the data for a specific week.

The week number can also be used to group data. For example, you could use the week number to group data by week to see how the data changes over time.

The week number is a useful tool for analyzing data in Power BI. It can be used to filter, group, and visualize data in a variety of ways. By using the week number, you can gain a deeper understanding of your data and make more informed decisions.

How do I get the week number from a date in Power BI?

There are a few ways to get the week number from a date in Power BI.

• Use the DATEPART function. The DATEPART function returns a part of a date, such as the day, month, or year. To get the week number, you can use the following formula:

“`
=DATEPART(“week”, date)
“`

• Use the WEEKNUM function. The WEEKNUM function returns the week number of a date, based on the first day of the week. By default, the first day of the week is Sunday. To change the first day of the week, you can use the following formula:

“`
=WEEKNUM(date, firstDayOfWeek)
“`

• Use the ISOWEEKNUM function. The ISOWEEKNUM function returns the week number of a date, based on the international standard ISO 8601. The ISO week starts on a Monday and ends on a Sunday. To get the ISO week number, you can use the following formula:

“`
=ISOWEEKNUM(date)
“`

What is the difference between the DATEPART function and the WEEKNUM function?

The DATEPART function and the WEEKNUM function both return the week number of a date. However, there are a few key differences between the two functions.

• The DATEPART function returns a number, while the WEEKNUM function returns a text string.
• The DATEPART function can be used to return the week number of any date, regardless of the first day of the week. The WEEKNUM function can only be used to return the week number of a date that is based on the first day of the week that is specified in the function.
• The DATEPART function is more flexible than the WEEKNUM function, because it can be used to return the week number of any part of a date, not just the whole date.
