Custom Date Format Output in Tableau

You have a date field 'Order Date'. You apply the custom date format MMM dd, yyyy in Tableau. What will be the output for the date 2024-06-15?

A Jun 15, 2024

B 06 15, 2024

C 15 Jun, 2024

D 2024-06-15

💡 Hint

MMM means the short month name, dd is day with leading zero, yyyy is full year.

The format MMM dd, yyyy shows the abbreviated month name, day number, then full year. So June 15, 2024 becomes 'Jun 15, 2024'.

Choosing the Correct Custom Date Format for a Dashboard

You want to display dates on a sales dashboard as 'Friday, June 14, 2024'. Which custom date format string should you use in Tableau to achieve this?

A ddd, MMM dd, yyyy

B dddd, MMMM dd, yyyy

C MM/dd/yyyy

D yyyy-MM-dd

💡 Hint

dddd gives full weekday name, MMMM full month name.

The format dddd, MMMM dd, yyyy shows full weekday name, full month name, day, and year, matching the desired output.

Understanding Tableau Date Format Tokens

Which of the following statements about Tableau custom date format tokens is correct?

A 'dd' displays the day of the week, while 'ddd' displays the day of the month.

B 'HH' displays the hour in 12-hour format, while 'hh' displays the hour in 24-hour format.

C 'MM' displays the full month name, while 'MMM' displays the month as a number.

D 'yy' displays the two-digit year, while 'yyyy' displays the four-digit year.

💡 Hint

Think about how years and months are commonly formatted.

In Tableau, 'yy' shows two-digit year (e.g., 24), 'yyyy' shows four-digit year (e.g., 2024). 'MM' is month number with leading zero, 'MMM' is abbreviated month name. 'dd' is day of month, 'ddd' is abbreviated weekday. 'HH' is 24-hour, 'hh' is 12-hour.

Fixing Incorrect Date Format Output

You applied the custom date format MMM-dd-yyyy in Tableau but the output shows Jun-15-24 instead of Jun-15-2024. What is the cause?

A Using 'yy' instead of 'yyyy' causes the year to show as two digits.

B Using 'MMM' causes the month to show as a number instead of name.

C Using 'dd' causes the day to be omitted from the output.

D Using dashes '-' is invalid in Tableau date formats.

💡 Hint

Check the year token length.

The token 'yy' shows two-digit year (e.g., 24). To show four-digit year (2024), use 'yyyy'. The dashes and 'MMM' are correct.

Designing a Custom Date Format for International Audience

You need to create a Tableau dashboard for users in the US and Europe. The date should show as June 15, 2024 for US users and 15 June 2024 for European users. Which approach is best to handle this with custom date formats?

A Use the format 'yyyy-MM-dd' which is neutral and understood internationally.

B Use a single format 'dd MMMM, yyyy' for all users to keep it consistent.

C Create two calculated fields with formats 'MMMM dd, yyyy' and 'dd MMMM yyyy' and show based on user locale.

D Let users manually change the date format in Tableau Desktop settings.

💡 Hint

Think about how to customize display based on user location.

Creating two calculated fields with different formats and showing them based on user locale allows correct regional date display. Single format or neutral ISO format may confuse users. Manual change is not user-friendly.
