What is the traditional phrase used on someone's name day, equivalent to 'happy birthday' but for a patron saint's feast?

• A kali orexi
• B sto kalo

• D chronia polla ✓

'Chronia polla' (literally 'many years') is the standard greeting for name days, birthdays, and major holidays; name days celebrate the feast of one's patron saint and are often more significant than birthdays.
