On the other hand, the %a character sequence returns the total number of days that have passed between two dates. Their value will never be greater than 31. The %D and %d character sequences return the number of days between two dates after subtracting the number of months and years. The days returned by %D or %d and %a are different. You just have to pass the %a character sequence to the format() method. Once you have computed the difference between two dates using the diff() method, getting the number of days between them is easy. The DateTime class takes care of everything for you like different number of days in different months, leap years and daylight saving time. Output: 08 years 01 months and 24 days 06 hours 43 minutes and 38 seconds. Output: 34 years 02 months and 09 days 00 hours 00 minutes and 00 seconds.Įcho $interval->format('%Y years %M months and %D days %H hours %I minutes and %S seconds.')

$interval = $first_date->diff($second_date) r: This will output “-” when negative and nothing when positive.Įxample: Calculated the number of years, months and days between two dates.R: This will output “-” when negative and “+” when positive.Single digits will be followed by leading zero. f: This will output microseconds numerically with at least 6 digits.F: This will output microseconds numerically with at least 6 digits.s: This will output seconds numerically without any leading zeroes.S: This will output seconds numerically with at least 2 digits.i: This will output minutes numerically without any leading zeroes.I: This will output minutes numerically with at least 2 digits.h: This will output hours numerically without any leading zeroes.H: This will output hours numerically with at least 2 digits.a: This will output the total number of days computed by DateTime::diff() or (unknown) otherwise.d: This will output days numerically without any leading zeroes.

D: This will output days numerically with at least 2 digits.

m: This will output months numerically without any leading zeroes.

M: This will output months numerically with at least 2 digits.

y: This will output years numerically without any leading zeroes.

Y: This will output years numerically with at least 2 digits.

%: This will output a literal % character.

Here is a list of all the format characters and their usage: All these characters must be prefixed by a percent sign (%). This method accepts different characters as part of its string parameter. Once you have the DateInterval, you can use the format() method to format it according to your needs. It returns a DateInterval object which contains information like the number of years, months and days between two given dates. The DateTime class has a diff() method which calculates the difference between two DateTimeobjects. Get the Difference Between Two Dates Using DateTime::diff() Simply converting two dates to a timestamp and subtracting the values is not reliable in all cases. The PHP DateTime class takes care of all this. For example, you have to take both leap years and daylight saving time into consideration. There are a lot of things that can go wrong if you are not careful. Calculating the difference between two dates is not as easy as it sounds.
