How to Say “Have a good day!” in Welsh

‘Have a good day!’ (or ‘Have a nice day!‘) is one of the most common ways in English to conclude a conversation or end a message on a positive note besides the various forms of goodbye. So, naturally, when an English person starts learning Welsh, it is also one of the first expressions he or she is eager to translate!

The first thing you should know is that you can’t translate ‘have a good day‘ word-for-word in Welsh when it is intended as an imperative rather than a neutral statement. A natural sounding alternative is to use the verb ‘enjoy’ instead which is mwynhau (northern) / joio (southern).

Mwynha dy ddiwrnod! = Enjoy your day! (informal)
Mwynhewch eich diwrnod! = Enjoy your day! (formal and plural)

Joia dy ddiwrnod! = Enjoy your day! (informal)
Joiwch eich diwrnod! = Enjoy your day! (formal and plural)

It is also very common to drop diwrnod entirely and use Mwynha! / Mwynhewch! / Joia! / Joiwch! on their own.

Dw i’n mynd i’r parti rwan. – Ok, joia!

I’m going to the party now. – Ok, enjoy!

Note that the word da (good) may be replaced with other similar adjectives like braf (nice, fine) or gwych (great).

More often than not, you’ll hear a range of other expressions in Welsh that don’t translate as ‘have a good day‘ but serve more or less the same purpose in that they close off the conversation in a friendly manner. These include:

pob hwyl (literally “every fun”)
hwyl fawr (literally “big fun”)
tan y tro nesa (literally “until next time”)
wela i di (literally “I will see you”)
