Learn Arabic (Modern Standard): يبدأ الربيع في مارس.

In Arabic, it is very common to start a sentence with the verb. This is known as a verbal sentence. So, instead of the English word order 'Spring begins', Arabic prefers 'Begins the spring'.

Why do we use the verb form يبدأ instead of تبدأ here?

The verb must match the gender of its subject. Because the word for spring, الربيع, is masculine, we use the masculine present tense verb form يبدأ. If the subject were feminine, the verb would start with the letter taa instead of yaa.

Why does الربيع have the definite article ال when the English translation is just 'Spring'?

In Arabic, seasons like spring, summer, winter, and autumn are treated as definite nouns when talking about them generally. Therefore, you must attach the definite article ال (the), literally saying 'the spring'.

Is مارس the only way to say 'March' in Arabic?

While مارس is a direct phonetic translation used in many Arab countries (like Egypt and the Gulf), countries in the Levant region (such as Lebanon and Syria) use a different set of traditional month names. Over there, March is called آذار.
