@SHANNUM17356877 you've not given us a lot to go by...

However I'll provide you with a comprehensive explanation of how to implement this feature in your applications.

Here's a structured guide on how to work with day of the week functionality in Pega:

1. Using Date Properties
   • Always use DateTime properties instead of simple Date properties for persistent objects
   • This ensures proper handling across different time zones and work calendars
   • The system provides built-in functions for working with dates
2. Implementing Day of Week Logic
   • Use the pxDayOfWeek function in when() conditions
   • Returns values 1 (Sunday) through 7 (Saturday)
   • Can be used in decision rules and activities
3. Practical Examples

For Weekday Check:

when(pxDayOfWeek(property) > 1 and pxDayOfWeek(property) < 7)

For Weekend Check:

when(pxDayOfWeek(property) = 1 or pxDayOfWeek(property) = 7)

4. Common Use Cases
   • Automating processes for business days only
   • Scheduling activities outside peak hours
   • Implementing different business logic for weekdays vs. weekends
   • Calculating service level agreements (SLAs) based on business days

Here's a visual representation of how day of week functionality works in Pega:

Additional Considerations:

• Always account for different time zones when working with dates
• Consider using work calendars for more complex business day calculations
• Remember to handle holidays separately from regular weekend checks
• Test your date logic across different scenarios and time zones
