March 30 in English: The Complete Guide to Date Formats and Pronunciation

When it comes to writing dates in English, March 30 often causes confusion for non-native speakers. This specific date sits in that tricky transitional period between spring's arrival and winter's departure, making it particularly memorable in many cultures. The way we write and say this date varies significantly between American and British English, with each tradition having its own logical system that developed over centuries of linguistic evolution.

In the United States, March 30 would typically be written as 3/30/2025 in numerical form. This month-first approach stems from how Americans naturally speak dates aloud we say "March thirtieth" rather than "the thirtieth of March."

Americans pronounce this date as "March thirtieth" or "March thirty" in casual speech. The ordinal number ("thirtieth") is preferred in formal contexts, while the cardinal number ("thirty") appears more in everyday conversation.

The British pronunciation maintains clearer distinction between the day and month compared to the American version.

Beyond the US and UK systems, international organizations often use the ISO 8601 standard which formats March 30 as 2025-03-30.
