Countdown script

How it works:
ceil() is just a "round up" function. So, for example, ceil(4.3) returns 5.

mktime() returns the unix timestamp for a date, i.e. converts a date to a number: December 25th 2006 returns 116702640

time() returns the unix timestamp for the time now.

Unix time is the number of seconds since midnight of January 1st, 1970

The example below counts down in days as 86400 is the number of seconds in a day, if you wanted to divide by another amount of time you'd need to change this to the number of seconds in that time. E.g. changing the number to any of these:
1440 = minutes
3600 = hours
86400 = days
604800 = weeks
