Learn Farsi: در فروردین باران می‌آید.

In Farsi, there isn't a single verb that means "to rain." Instead, you use a combination of the noun باران (rain) and the verb آمدن (to come). So, you literally say "rain comes" instead of "it rains."

Does Farsi use a word for "it" like we do in the English phrase "it rains"?

No, Farsi doesn't use dummy subject words like "it" for weather. Because the sentence is structurally built as "rain comes," the word باران (rain) is the actual subject doing the action.

When exactly is the month of فروردین (Farvardin)?

فروردین is the first month of the Iranian solar calendar. It begins exactly on the spring equinox (usually March 21st) and marks the start of spring, a season well known for its rain showers.

Could می‌آید also mean "it is raining right now"?

Yes! The present tense prefix می is used for both actions happening right now (continuous) and general facts (habitual). By itself, باران می‌آید can mean "it is raining." However, because this sentence mentions a whole month (در فروردین), context tells us it means the habitual "it generally rains."
