In PHP, what considerations should be made when converting between Unix timestamps and human-readable dates for specific days of the week, such as Sunday and Monday?

When converting between Unix timestamps and human-readable dates for specific days of the week, such as Sunday and Monday, it's important to consider the timezone in which the conversions are being made. This ensures that the dates are accurate and consistent across different time zones. Additionally, using PHP's date() function with the 'l' format specifier can help retrieve the day of the week in its human-readable form.

// Set the timezone
date_default_timezone_set('America/New_York');

// Convert Unix timestamp to human-readable date
$timestamp = time();
$dayOfWeek = date('l', $timestamp);

echo "Today is: " . $dayOfWeek;
