# Add Holiday or Event

This option enables you to add a country-specific holiday and event to the Holiday and Event data set for identification within the Weekdays and Holidays report. You can also edit the existing Holiday and Event Data Set.

### To Add a Holiday or Event:

| 8 | Enter a name for the event in the Holiday or Event Name text box.

| 8 | Enter the start date and end date in the appropriate text boxes. Dates must be formatted as DDMMMYYYY where DD is the two-digit day, MMM is the three-letter abbreviation for the month, and YYYY is the four-digit year.

| 8 | Select applicable countries and click to add the country to list of affected countries. Note: Available countries are taken from your defined study.

| 8 | Click to add the event.

Only one holiday or event can be specified at a time. However, additional holidays or events can be added to the data set by running the application again for each new event.
