Calendar Table

[azeemnazim]

Hi,  I want to know what is the best way to create a calendar table and why a calendar table is that necessary to create. How to create one in query editor?

Try using the following code for creating a calendar which includes the "FullDate4Sort" column to sort calendar in ascending dates. Feel free to add whatever columns you need with the Format and Date functions.

CALENDAR = ADDCOLUMNS(CALENDAR(DATE(2018,1,1),DATE(2030,12,31)),"FullDate4Sort",FORMAT([Date],"YYYY/MM/DD"),"DateAsInteger",FORMAT([Date],"YYYYMMDD"),"Year",YEAR([Date]),"MonthNumber",FORMAT([Date],"MM"),"YearMonthNumber",FORMAT([Date],"YYYY/MM"),"MonthNameShort",FORMAT([Date],"mmm"), "MonthNameLong",FORMAT([Date],"mmmm"), "DayOfWeekNumber",WEEKDAY([Date],1), "DayOfWeek",FORMAT([Date],"dddd"), "DayOfWeekShort",FORMAT([Date],"ddd"),"Quarter","Q"& FORMAT([Date],"Q"), "YearQuarter",FORMAT([Date],"YYYY") & "/Q" & FORMAT([Date],"Q"))

@azeemnazim - Calendar tables are just a common dimension in many data models and Power BI wants you to use a star schema data model. You need a calendar table for many time intelligence functions to operate.

But, if you don't want one, there are other ways. You may find this helpful - https://community.powerbi.com/t5/Community-Blog/To-bleep-With-Time-Intelligence/ba-p/1260000

Also, see if my Time Intelligence the Hard Way provides a different way of accomplishing what you are going for.

Hey @azeemnazim ,

Creating a calender table is very easy using this m query:

List.Dates(start as date, count as number, step as duration)

List.Dates(#date(2011, 12, 31), 5, #duration(1, 0, 0, 0))

12/31/2011 12:00:00 AM

1/1/2012 12:00:00 AM

1/2/2012 12:00:00 AM

1/3/2012 12:00:00 AM

1/4/2012 12:00:00 AM

Why calender tables is required?

• It allows you to aggregate data by non-standard columns (think your company’s financial year, or your timesheet weeks, or the Mayan calendar!).
• It gives you access to all of the wonderful time-intelligence functions in DAX, with names like TOTALYTD and CLOSINGBALANCE. Without a calendar table these won’t work.

If your problem is solved then accept this reply as solution.

Thank you

Hey,

this article provides a lot of examples on how to use a calendar table:

https://www.daxpatterns.com/time-patterns/

This article explains why one should not use a "one-table" solution and strive for a star schema data model, where a calendar table is just one of the dimension tables:

Here is an example creating a calendar table using power query:
