NAME Date::Biorhythm - a biorhythm calculator SYNOPSIS Usage use Date::Biorhythm; my \$bio = Date::Biorhythm->new({ birthday => Date::Calc::Object->new(0, 1970, 1, 1), name => 'Unix', }); my \$i = 0; my \$limit = 365; \$bio->day(Date::Calc::Object->today); while (\$i < \$limit) { print \$bio->value('emotional'), "\n"; \$bio->next; \$i++; } DESCRIPTION I find biorhythms mildly amusing, but I got tired of visiting http://www.facade.com/biorhythm and having to deal with their web-based form for date entry. I vaguely remembered there being a Perl module for biorhythm calculation, but I couldn't find it on CPAN. Further investigation finally led me to BackPAN where I found Date::Biorhythm 1.1 written by Terrence Brannon (a long time ago). Wanting an excuse to try Moose out, I decided to make a new and modernized version of Date::Biorhythm, and this is the result. BUT WTF IS A BIORHYTHM? http://en.wikipedia.org/wiki/Biorhythm METHODS new The constructor. It takes on optional hashref that will accept the following keys: name, birthday, and day. name Get or set the name associated with this biorhythm. This will usually be a person's name. birthday Get or set the birthday used for this biorhythm. day Get or set the current day (which is represented by a Date::Calc::Object). next Go forward one day by incrementing \$self->day. prev Go backward one day by decrementing \$self->day. index Given a primary cycle (such as 'emotional', 'intellectual', or 'physical'), return how many days we are into the cycle. Note that the first day of the cycle returns 0. value Given a primary cycle or secondary cycle, return a value between -1 and 1 that represents the current amplitude in the cycle.
