Excel handles dates and time using a scheme in which dates are serial numbers and times are fractional values. For example, June 1, 2000 12:00 PM is represented in Excel as the number 36678.5, where 36678 is the date portion and .5 is the time portion.
If you have dates with time values and you want to extract only the date portion, you can use a formula that uses the INT function. So, assuming A1 contains the date and time, June 1, 2000 12:00 PM, the formula below returns just the date portion (36678):
1. With either method above, make sure you use a date format on the result that does not include a time. Otherwise, you'll see the time displayed as 12:00 AM.
2. For dates and times (which must be positive in Excel) there is no difference in using INT and TRUNC to extract an integer. But INT actually rounds numbers down to the nearest integer, which makes a difference when values are negative. See the TRUNC link below for more details.

The Excel INT function returns the integer part of a decimal number by rounding down to the integer. Note the INT function rounds down, so negative numbers become more negative. For example, while INT(10.8) returns 10, INT(-10.8) returns -11.
The Excel TRUNC function returns a truncated number based on an (optional) number of digits. For example, TRUNC(4.9) will return 4, and TRUNC(-3.5) will return -3. The TRUNC function does no rounding, it simply truncates as specified.
