Hi @cheezy ,
Could you please share more details? Which trigger would you like to use? Is it a scheduled flow which runs once a month the day before the first Thursday?
If this is the case, then you need to use a Recurrence trigger with a trigger condition:


@equals(addDays(startOfMonth(utcNow()), mod(sub(10, dayOfWeek(startOfMonth(utcNow()))), 7), 'yyyy-MM-dd'), utcNow('yyyy-MM-dd'))
Best regards,
