Add option to Recur: ignore holidays
then flags like NBD ignore holidays (but count weekends)
When calculating holidays, use this option by default to simplify
holidays. Then, order of definitions is not important.
Add options:
onlyiso8601, etc. to parse
no-delta-secs (not delta as a plain number)
no-timezone
Can I reduce the number of timezone modules loaded when parsing a date
with an abbreviation or offset by loading one and testing it before
loading a second?
Make sure the following work:
1*12:0:24:0:0:0*FW1 = Christmas Day (observed)
December 25 2015 = Christmas Day
Add a new type of recurrence (???):
*Christmas Day*NWD
Add ability to supply holidays via. a list rather than a config file.

Everywhere a timezone can be entered, allow:

followed by an option:
std either STD or DST time, test STD first (default always)
dst either STD or DST time, test DST first

Change the Jan1Week1 variable to accept the values "m1-m7" (1st week contains
Jan X) or "d1-d7" (1st week contains the 1st dX day of week ... so d1
means that the 1st week of the year contains the 1st Monday).
Free up the '%u', '%h', and '%X' printf formats. Reserve '%X' for
extended formats (%Xa, %Xb, ...).

# TO CONSIDER
########################################################################
Special date formats in language file:
extra{LABEL} = [ ... ] extra words of type LABEL
offset_date =>
FORMAT => 'OFFSET'
where FORMAT is similar to parse_format
%LABEL is a regexp with any of the words
OFFSET can include %y, %d, %w, %m, %h, %mn, $s in them
same for offset_time, times, and others
ex.
offset_time => { "%h o'clock" => "%h:00:00" }
Support some of the special Russian dates supplied by Yuri Nikulin
Add a method:
($date0,$date1) = $date->week_range();
where $date0 and $date1 are the start and end of the week containing
$date. Ha Quach
Add Date_LocaleInit which calls Date_Init and then sets DateFormat
config varialbe. Benjamin Low
Essentially, I use POSIX::strftime to print a known date in the locale
'native' format ('%x'), and parse the result to determine d/m/y, m/d/y,
or y/m/d.
Here's what I do for Date::Parse, perhaps for your module you could just
substitute a default value for DateFormat:
sub _dmorder
# determine the "natural" day/month order for the current locale
# - returns a sub which will expect two arguments (month, day) and
# return the arguments swapped as appropriate
{
# %x - preferred (year, month, day) representation
# - some examples: 1999-12-31, 31/12/99, 30.12.1999, 12/31/99
my @d = (POSIX::strftime('%x', 0, 0, 0, 31, 12-1, 99) =~
/(\d+)\D+(\d+)\D+(\d+)/);
# check we got one each of "31", "12", and "[19]99" back
$@ = "couldn't determine day,month order (got [@d])";
warn("$@\n"), return sub { @_ } unless @d == 3;
my %d; $d{$1} = $d{$2} = $d{$3} = 1;
warn("$@\n"), return sub { @_ }
unless ($d{31} and $d{12} and ($d{99} or $d{1999}));
if ($1 == 31) { $@ = undef; return sub { ($_[1], $_[0]) } }; # d/m/y
if ($2 == 31) { $@ = undef; return sub { ($_[0], $_[1]) } }; # m/d/y
if ($3 == 31) { $@ = undef; return sub { ($_[0], $_[1]) } }; # y/m/d
return sub { @_ }; # undetermined, use default
}
*dmorder = _dmorder();
# and then later in Parse::Date, after month/day regexps (\d+/\d+)...
- ($month, $day) = ($1, $2); becomes...
+ ($month, $day) = dmorder($1, $2);
Make DateFormat variable handle y/m/d y/d/m m/d/y and d/m/y formats
in addition to m/d vs. d/m . Also, make "%D" and "%x" UnixDate formats
use this variable. Benjamin Low

# GRANULARITY
########################################################################
$flag=&Date_GranularityTest($date,$base,$granularity [,$flags] [$width])
$date and $base are dates
$granularity and $width are deltas
$flags is a list of flags
To test if a day is one of every other Friday (starting at Friday
Feb 7, 1997), go:
$base=&ParseDate("Friday Feb 7 1997");
$date=&ParseDate("...");
$granularity=&ParseDateDelta("+ 2 weeks");
$flag=&Date_Granularity($date,$base,$granularity,"exact");
If $flag is 1, the $date is a 2nd Friday from Feb 7.
The most important field in $granularity is the last non-zero element.
In the above example, 2 weeks returns the delta 0:0:14:0:0:0 so the
last non-zero element is days with a value of 14.
If $flags is empty, $date is checked to see if it occurs some multiple
of 14 days before or after $base. In this case, hourse, minutes, and
seconds are completely ignored.
If $flags contains the words "before" or "after", $date must come
before or after $base.
If $flags contains any other options, or if $width is passed in, the
test is treated in an approximate way. A flag of "approx" forces this
behavior.
If $width is not passed in in an approximate comparison, it defaults
to 1 in the last non-zero element. Here, the default width is 1 day.
If the flag "half" is used, the width (default or passed in) is
halved.
For example if $width is 1 day, add a multiple of $granularity to
$base to get as close to $date as possible. If $date is within plus
or minus 1 day of this new base, the test is successful. A flag of
"plus" or "minus" means that $date must be with plus 1 day or within
minus one day of this new base. Flags of "before" or "after" work
as well.
@list=&Date_GranularityList($date,$N,$granularity)
Returns a list of $N dates AFTER $date which are created by adding
$granularity to $date $N times. If $N<0, it returns $N dates BEFORE
$date (the list is in chronological order).
Make it work in business mode as well which will return only working
days. Example, every other friday and it can be told that if friday
falls on a holiday to return either thursday or the following monday
or leave it out.
