# Date and Time Patterns

When defining data type options for date and time data, you can create your own custom date or time pattern if the predefined ones do not meet your needs. To create a date or time pattern, use the notation described in the following table. For example, this pattern:

dd MMMM yyyy

Would produce a date like this:
