How do you say is the day in maori?

There's no single word in Māori that translates directly to "is the day".

Here's how you would express it, depending on the context:

For asking what day it is:

* He aha te ra? - This literally means "What is the day?"

* He aha te rangi? - This literally means "What is the weather?" but is commonly used to ask about the day of the week.

For stating the day:

* You would use the specific day of the week, such as:

* Rāhina - Monday

* Rātū - Tuesday

* Rāapa - Wednesday

* Rāpare - Thursday

* Rāmere - Friday

* Rāhoroi - Saturday

* Rātapu - Sunday

For describing the quality of the day:

* You would use descriptive words like:

* Ataahua - Beautiful

* Māhana - Warm

* Mātao - Cool

* Huka - Cloudy

* Uru - Windy

Examples:

* He aha te ra? - What is the day?

* Ko Rāhina te ra. - It is Monday.

* He ra ataahua tēnei. - This is a beautiful day.
