% =========================================================================
%            Calculate Mouse Age (Years, Months, Weeks) 
% =========================================================================

% --- 1. Define Dates ---
% Define the mouse's birth date
birthDate = datetime('2025-02-13');
% Define the capture date
shotDate = datetime('2025-05-30');

% --- 2. Calculate Age and Month Age ---
% For years and months, calendarDuration is what we want.
durationCal = between(birthDate, shotDate);
ageInYears = calyears(durationCal);
ageInMonths = calmonths(durationCal);

% --- 3. Calculate Week Age ---
durationFixed = shotDate - birthDate;
totalDays = days(durationFixed);
ageInWeeks = totalDays / 7;

% --- 4. Format and Display Results ---
% The output section remains the same.
outputString = sprintf([...
    'Mouse Age Calculation Result:\n' ...
    '-------------------\n' ...
    'Age: %.4f years\n' ...
    'Month Age: %.4f months\n' ...
    'Week Age:   %.4f weeks'], ...
    ageInYears, ageInMonths, ageInWeeks);

% Display the final result in the command window
disp(outputString);

Output

Mouse Age Calculation Result:
-------------------
Age: 0.0000 years
Month Age: 3.0000 months
Week Age:   15.1429 weeks
