Congratulations on your new job!

Always Plural
Even when congratulating one person, this word is always used in its plural form, ending in -s.
Using 'Feliz' instead
Mistake: “Using '¡Feliz!' to mean 'Congratulations.'”

ah-che-beˌatʃe ˈβe

¡hb! Que cumplas muchos más.
Happy birthday! May you have many more.
Feliz hb para tu hermano.
Happy birthday to your brother.
No pude ir a tu hb, lo siento.

Borrowed from English
This is an 'Anglicism'—a term borrowed from English 'Happy Birthday.' Even though the Spanish words are 'Feliz Cumpleaños,' many people use the English letters.
Gender and Number
When used as a noun (the event), it is masculine (el hb) because it replaces 'el cumpleaños,' which is masculine.
Confusing the meaning
Mistake: “Sending 'hb' as a greeting on a normal day.”
Correction: Make sure you check the date! Outside of specific regions, this only means Happy Birthday.
Choosing Between 'Felicidades' and 'HB'
The most common mistake is using the very informal abbreviation 'hb' in situations that call for a more standard greeting. 'Felicidades' is a safe and widely understood option for most birthday wishes, while 'hb' should be reserved for casual online interactions.
