When a PHP application needs to uses easter_date to process its supported input, choosing the right API and checking its results helps keep code understandable and dependable. This guide explains easter_date with focused examples and important details.

What Is easter_date in PHP?

easter_date uses easter_date to process its supported input. Only works for its supported year range; the returned Unix timestamp represents midnight in the default time zone and may vary across environments.

Syntax:

easter_date(year, mode) : int

Parameters and return value: Parameters: <optional> ?int $year = null; <optional> int $mode = CAL_EASTER_DEFAULT. Check the return value or modified object rather than assuming the operation always succeeds.

Important: The code examples use representative input rather than production credentials. Confirm that the required PHP extension is installed.

Example 1: Basic Usage

Start with a compact input so the main operation is visible.

<?php

echo easter_date(2026);

Output:

1775347200

Uses easter_date to process its supported input. Only works for its supported year range; the returned Unix timestamp represents midnight in the default time zone and may vary across environments.

Example 2: A Different Input

The next example changes the input or option to illustrate another behavior.

<?php

print_r(date("Y-m-d", easter_date(2027)));

Output:

2027-03-28

Compare this result with the first example. Only works for its supported year range; the returned Unix timestamp represents midnight in the default time zone and may vary across environments.

Practical Example: Applying the Function

This example combines the API with a realistic processing step and shows where to check its result.

<?php

foreach ([2026,2027,2028] as $year) { echo $year . ": " . gmdate("Y-m-d", easter_date($year)) . PHP_EOL; }

Output:

2026: 2026-04-05
2027: 2027-03-28
2028: 2028-04-16

Adapt the inputs to your application and validate the output before storing or displaying it. Only works for its supported year range; the returned Unix timestamp represents midnight in the default time zone and may vary across environments.

Important Behavior and Edge Cases

  • Main purpose: Uses easter_date to process its supported input.
  • Errors and boundaries: Only works for its supported year range; the returned Unix timestamp represents midnight in the default time zone and may vary across environments.
  • Environment: The code examples use representative input rather than production credentials. Confirm that the required PHP extension is installed.
