You could make a check like this: (Warning: pseudo-coding)
[%GetStartOfCurrentWeek%] is usually sunday, adjust the following query accordingly.
if ('[%CurrentDateTime%]' > '[%GetStartOfCurrentWeek%] - [%DayLength%]' and '[%CurrentDateTime%]' <= '[%GetStartOfCurrentWeek%] + 2 * [%DayLength%]') then WEEKEND = true else WEEKEND = false
You would have to adjust it a bit based on when you want the weekend to start etc. but this way you use the datetime placeholders, instead of resorting to string matching.
You could use a Java action to return the DOW:
Calendar cal = Calendar.getInstance(); cal.setTime(InputDate); int dow = cal.get(Calendar.DAY_OF_WEEK);
You would need to add
import java.util.Date; import java.util.Calendar;
In the documentation, I see that
formatDateTime($object/Date1,'EEE, d MMM yyyy HH:mm:ss Z')
returns 'Sun, 8 Jun 2008 10:12:01 +0200'
So it will be possible if you check in the microflow if currentdatetime = Sun or Sat (make an exclusive split)
Perhaps there are other/better options
This solution is ok if you mind the capitals. The only other way I found with Mendix is daysBetween and take a Saturday as reference. But yours is better.
It is a good habit to make a settings boolean that allows you to enable and disable the microflow run-time. The scheduled task starts a MF that first checks this boolean.
