Date Calculator is a simple tool for calculating date differences. It returns the calculated date difference based on the dates provided.
The Date Calculator API provides a simple, reliable way to integrate date calculator functionality into your applications. Built for developers who need production-ready date calculator capabilities without the complexity of building from scratch.
Quick Start
Using JavaScript
async function callDateCalculatorAPI() {
try {
const params = new URLSearchParams({
start: '2022-01-01',
end: '2024-08-31'
});
const response = await fetch(`https://api.apiverve.com/v1/datecalculator?${params}`, {
method: 'GET',
headers: {
'x-api-key': 'YOUR_API_KEY_HERE'
}
});
const data = await response.json();
console.log(data);
} catch (error) {
console.error('Error:', error);
}
}
callDateCalculatorAPI();Using cURL
curl -X GET "https://api.apiverve.com/v1/datecalculator?start=2022-01-01&end=2024-08-31" \
