Hi,
NOW() > Start AND NOW() < End
Assuming Start/End - are the day of someone’s birthday it should work. ie:
Start 2015-09-01 00:00:00
End 2015-09-01 23:59:59
Then with this filter it will show only record(s) of people that have birthday on that specific day.
As for dataSet you would need just dates and [Name] I guess, then in ticker add this filter and in appearance the [Name] tag.
