Solution: Weeks until Christmas

Here is a possible solution to the task.

Code

my $days = Date.new(2026, 12, 25) - Date.new(2026, 6, 27);
say "{$days div 7} weeks and {$days % 7} days";

🦋 You can find the source code in the file days-until-christmas.raku.

Output

25 weeks and 6 days

Comments

Subtracting one Date from another returns the number of days between them — here 181 — so no manual counting of the days in each month is needed. The later date is written first, so the result is positive.
Integer division div gives the whole number of weeks (181 div 7 is 25), and the modulo operator % gives the days left over (181 % 7 is 6).
