This kind of cheats. If it's a negative number it assumes that it's after christmas and will just print the second line. you could do some more logic to make it return the actual number until the next christmas, but I didn't want to gum it up too much.
I am taking a class in UNIX and have written a script that needs to countdown from a number that is read in from the keyboard to zero. If no number is given the start of the countdown should default to 10.
I can't get this to do the default

Hi guys, I've found two nifty little scripts on these forums one which detects if the F5 key has been pressed:

Hi all,

Hello. I am pretty new to unix and shell scripting and I was wondering if there might be a way to banner a countdown timer inside a script.

easter_date
EASTER_DATE(3) 1 EASTER_DATE(3)easter_date - Get Unix timestamp for midnight on Easter of a given yearSYNOPSIS
int easter_date ([int $year = date("Y")])
DESCRIPTION
Returns the Unix timestamp corresponding to midnight on Easter of the given year.
Warning
This function will generate a warning if the year is outside of the range for Unix timestamps (i.e. before 1970 or after 2037).
The date of Easter Day was defined by the Council of Nicaea in AD325 as the Sunday after the first full moon which falls on or after the
Spring Equinox. The Equinox is assumed to always fall on 21st March, so the calculation reduces to determining the date of the full moon
and the date of the following Sunday. The algorithm used here was introduced around the year 532 by Dionysius Exiguus. Under the Julian
Calendar (for years before 1753) a simple 19-year cycle is used to track the phases of the Moon. Under the Gregorian Calendar (for years
after 1753 - devised by Clavius and Lilius, and introduced by Pope Gregory XIII in October 1582, and into Britain and its then colonies in
September 1752) two correction factors are added to make the cycle more accurate.
PARAMETERS
o $year
- The year as a number between 1970 an 2037. If omitted, defaults to the current year according to the local time.
RETURN VALUES
The easter date as a unix timestamp.
EXAMPLES
Example #1
easter_date(3) example
<?php
echo date("M-d-Y", easter_date(1999)); // Apr-04-1999
echo date("M-d-Y", easter_date(2000)); // Apr-23-2000
echo date("M-d-Y", easter_date(2001)); // Apr-15-2001
?>
NOTES
Note
easter_date(3) relies on your system's C library time functions, rather than using PHP's internal date and time functions. As a con-
sequence, easter_date(3) uses the TZ environment variable to determine the time zone it should operate in, rather than using PHP's
default time zone, which may result in unexpected behaviour when using this function in conjunction with other date functions in
PHP.
As a workaround, you can use the easter_days(3) with DateTime and DateInterval to calculate the start of Easter in your PHP time
zone as follows:
<?php
function get_easter_datetime($year) {
$base = new DateTime("$year-03-21");
$days = easter_days($year);
return $base->add(new DateInterval("P{$days}D"));
}
foreach (range(2012, 2015) as $year) {
printf("Easter in %d is on %s
",
$year,
get_easter_datetime($year)->format('F j'));
}
?>
The above example will output:
Easter in 2012 is on April 8
Easter in 2013 is on March 31
Easter in 2014 is on April 20
Easter in 2015 is on April 5
SEE ALSO easter_days(3) for calculating Easter before 1970 or after 2037 .
