Nuget GitHub GitHub Workflow Status (branch) GitHub issues

The Age Calculator is a library (based on the Gregorian calendar) which can be used to calculate the age between two dates and output years, months, days and time components.

In addition to the default calculation algorithm, it can be configured so that Feb 29<sup>th</sup> of a leap year be considered as Feb 28<sup>th</sup> of a non-leap year (making 1-year cycle) with switch of a flag. By default, the flag is off.

How To Use (C# Code)

/* There are three ways to calculate the age between two dates */
using AgeCalculator;
using AgeCalculator.Extensions;

public void PrintMyAge()
{
    // Date of birth or from date.
    var dob = DateTime.Parse("10/03/2015");
    
    // #1. Using the Age class constructor.
    var age = new Age(dob, DateTime.Today); // as of 09/19/2021
    Console.WriteLine($"Age: {age.Years} years, {age.Months} months, {age.Days} days, {age.Time}");
    
    // #2. Using DateTime extension.
    age = dob.CalculateAge(DateTime.Today); // as of 09/19/2021
    Console.WriteLine($"Age: {age.Years} years, {age.Months} months, {age.Days} days, {age.Time}");
    
    // #3. Using the Age type's static function.
    age = Age.Calculate(dob, DateTime.Today); // as of 09/19/2021
    Console.WriteLine($"Age: {age.Years} years, {age.Months} months, {age.Days} days, {age.Time}");
}

// Output:
// Age: 5 years, 11 months, 16 days, 00:00:00
/* In this example, Feb 29 of a leap year is considered as Feb 28 of a non leap year. */
using AgeCalculator;
using AgeCalculator.Extensions;

public void PrintAge()
{
    // Example 1
    var dob = DateTime.Parse("02/29/2016");
    var toDay = DateTime.Parse("02/28/2021");
    var age = new Age(dob, toDay, true); // <- Switch the flag ON. Default is OFF.
    Console.WriteLine($"Example 1 - Age: {age.Years} years, {age.Months} months, {age.Days} days, {age.Time}");
    
    // Example 2
    dob = DateTime.Parse("02/29/2016");
    toDay = DateTime.Parse("02/28/2021 00:00:01");
    age = dob.CalculateAge(toDay, true); // <- Switch the flag ON. Default is OFF.
    Console.WriteLine($"Example 2 - Age: {age.Years} years, {age.Months} months, {age.Days} days, {age.Time}");
    
    // Example 3
    dob = DateTime.Parse("02/29/2016 00:00:02");
    toDay = DateTime.Parse("02/28/2021 00:00:01");
    age = Age.Calculate(dob, toDay, true); // <- Switch the flag ON. Default is OFF.
    Console.WriteLine($"Example 3 - Age: {age.Years} years, {age.Months} months, {age.Days} days, {age.Time}");
}

// Output:
// Example 1 - Age: 5 years, 0 months, 0 days, 00:00:00
// Example 2 - Age: 5 years, 0 months, 0 days, 00:00:01
// Example 3 - Age: 4 years, 11 months, 27 days, 23:59:59
