I'm very new to Node-Red and using it within Home Assistant. I am wanting to setup an automated Email that gets sent on a specific calculated day every month. I will try and break this down the best I can:
Email needs to get sent 10 working days before the same day a month later
Email cannot be sent on a weekend or a public UK holiday
So for example if the last Email sent was on the 20/04/2023, the next Email would need to be sent on the 5/05/2023. This is because the 20/05 is a Saturday, so 10 working days (Mon to Fri) would be the 8th, but the 8th is a Bank Holiday so cant be sent then either, so would then need to be sent on the Friday prior being the 5th.
I realise that Easter is a problem due its flexiable date.
I look forward to peoples responses to this.
