以下是完全适配你需求的修改后代码：

add_action( 'woocommerce_before_add_to_cart_form', 'delivery_estimate' );
function delivery_estimate() {
    global $product;
    // 非商品对象/缺货/不属于Available now分类直接返回
    if ( ! is_a( $product, 'WC_Product' ) || ! $product->is_in_stock() || ! has_term( 'available-now', '替换为你的自定义分类法Slug', $product->get_id() ) ) {
        return;
    }
    
    date_default_timezone_set( 'Europe/Tallinn' );
    $now = time();
    $today_16 = strtotime( 'today 16:00' );
    $deadline_ts = 0;
    $min_delivery_ts = 0;

    // 计算下单截止时间和最早配送时间
    if ( date( 'N' ) >= 5 ) { // 周五及以后
        $deadline_ts = strtotime( 'next monday 16:00' );
        $min_delivery_ts = strtotime( 'next tuesday' );
    } elseif ( $now >= $today_16 ) { // 工作日16点后
        $deadline_ts = strtotime( 'tomorrow 16:00' );
        $min_delivery_ts = strtotime( 'tomorrow +1 day' );
    } else { // 工作日16点前
        $deadline_ts = $today_16;
        $min_delivery_ts = strtotime( 'tomorrow' );
    }

    // 计算截止下单剩余时长
    $diff = $deadline_ts - $now;
    $hours = floor( $diff / 3600 );
    $mins = floor( ( $diff % 3600 ) / 60 );
    $countdown = "{$hours}小时{$mins}分钟";

    // 计算配送区间
    $delivery_start = date( 'n月j日', $min_delivery_ts );
    $delivery_end = date( 'n月j日', $min_delivery_ts + 86400 * 3 ); // 3为配送区间跨度天数，可自行调整

    // 输出提示
    echo "<br><div class='woocommerce-message' style='clear:both'><strong>若您在{$countdown}内下单，预计可在{$delivery_start}至{$delivery_end}之间完成配送。</strong></div>";
}
