Date::Calendar::Julian - Conversions from / to the Julian calendar
What is the peculiarity of 15 February for people using the Julian calendar? And can you please print it in, say, Dutch?
use Date::Calendar::Julian;
my Date $feb15-grg;
my Date::Calendar::Julian $palindrome-jul;
$feb15-grg .= new(2020, 2, 15);
$palindrome-jul .= new-from-date($feb15-grg);
say $palindrome-jul;
# --> 2020-02-02
$palindrome-jul.locale = 'nl';
say $palindrome-jul.strftime("%A %e %B %Y");
# --> zaterdag 2 februari 2020
my Str $s1 = $palindrome-jul.strftime("%Y%m%d");
if $s1 eq $s1.flip {
say "$s1 is a palindrome in YYYYMMDD format!";
}
$s1 = $palindrome-jul.strftime("%d%m%Y");
if $s1 eq $s1.flip {
say "$s1 is a palindrome in DDMMYYYY format!";
}
$s1 = $palindrome-jul.strftime("%m%d%Y");
if $s1 eq $s1.flip {
say "$s1 is a palindrome in MMDDYYYY format!";
}
The Perl & Raku Conference was scheduled to end on 1st August when using the Julian calendar. What is the corresponding Gregorian date?
use Date::Calendar::Julian;
my Date::Calendar::Julian $TPRC-Amsterdam-jul;
my Date $TPRC-Amsterdam-grg;
$TPRC-Amsterdam-jul .= new(year => 2020
, month => 8
, day => 1);
$TPRC-Amsterdam-grg = $TPRC-Amsterdam-jul.to-date;
say $TPRC-Amsterdam-grg;
# --> 2020-08-14
zef install Date::Calendar::Julian
or
git clone https://github.com/jforget/raku-Date-Calendar-Julian.git cd raku-Date-Calendar-Julian zef install .
