The phrase "August 1st" is used to refer to the first day of the month of August. In English, we usually state the month first, followed by the day, and then the year (if applicable).
For example, if someone asks you about a specific event or a birthday happening on August 1st, you could respond by saying "It's on August 1st." This date format is commonly used in English-speaking countries, such as the United States and Canada.
It's important to note that there might be some regional variations in date formats, which could affect how people write or say the date. However, "August 1st" is the generally accepted form in English.
