Have a blessed day in spanish
Que tengas un día bendecido is one way to express have a blessed day in Spanish. Que Dios te bendiga means may God bless you and conveys a related religious wish rather than the identical sentence.
Meaning and context
Use tengas when addressing one person informally. Tenga fits an usted form of address. The appropriate level of formality depends on the relationship and community. Religious wording can be warm in a shared faith setting, but it is not required for a friendly farewell.
Examples and usage
Que tenga un día bendecido is a more formal singular version. Que tengas un buen día expresses have a good day without the religious emphasis. Both can be kind wishes; the difference is the meaning you intend to communicate.

What to check
For a workplace message to someone whose preferences you do not know, a neutral good-day wish may be easier to interpret. Choose the phrase for the listener and situation, and do not describe one formula as the universal greeting across all Spanish-speaking communities.
