Understanding the Diamond Birthday Calculator
This calculator helps you determine the number of diamonds to gift or use as decorations for a diamond-themed birthday party. It's a fun way to celebrate milestones, especially for younger children who might enjoy a bit of sparkle!
How it Works:
The calculation is straightforward. You input the age of the birthday person and how many diamonds you'd like to associate with each year of their age. For instance, if someone is turning 7 and you want to give them 3 diamonds for each year they've lived, the calculator will tell you they need a total of 21 diamonds (7 years * 3 diamonds/year).
Why Use This Calculator?
- Party Planning: Great for planning decorations, favors, or even a special diamond-themed cake topper.
- Gift Ideas: Helps to quantify a "diamond" gift concept, whether it's actual diamond-shaped candies, craft diamonds, or even setting a budget for future diamond jewelry.
- Themed Celebrations: Adds an extra layer of fun and personalization to a glamorous birthday party.
Example:
Let's say Sarah is turning 8 and her parents want to give her 4 diamonds for each year she has been alive to celebrate her special "diamond" birthday. They would enter '8' for the age and '4' for the diamonds per year. The calculator would then show that Sarah needs a total of 32 diamonds (8 years * 4 diamonds/year).
var calculateDiamonds = function() {
var age = parseFloat(document.getElementById("age").value);
var diamondsPerYear = parseFloat(document.getElementById("diamondsPerYear").value);
var resultDiv = document.getElementById("result");
if (isNaN(age) || isNaN(diamondsPerYear) || age < 0 || diamondsPerYear < 0) {
resultDiv.innerHTML = "Please enter valid positive numbers for age and diamonds per year.";
return;
}
var totalDiamonds = age * diamondsPerYear;
resultDiv.innerHTML = "You will need a total of
" + totalDiamonds + " diamonds.";
};
