Birthday message translation

Hi all,
It’s my Dad’s birthday today and I thought it would be nice to send him a quick message in Welsh. Something nice and quick like “Happy birthday! I hope you had a good day”
I’ve worked this out as “Pen-blwydd hapus! Dw i’n gobeithio bod chi wedi cael dydd da”
I’m not sure about dydd da though… Does the above make sense?
Diolch :slight_smile:

Switch it to ‘diwrnod da’ and you’re right on the money - great work!..:seren:

Woohoo :slight_smile: Thanks!
