To say the date in Engpsh on the lunar calendar, you can use the phrase "Today is the [ordinal number] day of the [lunar month] month of the lunar calendar." For example, if today is the 5th day of the 8th lunar month, you could say "Today is the 5th day of the 8th month of the lunar calendar."
It's also worth noting that the lunar calendar is used primarily in East Asian cultures, and the way dates are referred to can vary depending on the language and cultural context. In Mandarin Chinese, for example, you might say "今天是农历[数字]月[数字]日" (jīntiān shì nónglì [shùzì] yuè [shùzì] rì), which means "Today is the [lunar month] month and [ordinal number] day of the lunar calendar."
