Form Spacing justify-content-between one <div> to left and one <span> to right

Question

您好，我正在尝试将 label 标记、文本和提交 input 类型对齐到左侧，并将 17 个总订单对齐到页面右侧垂直对齐带有日期 label 并与 paragraph 标签的末尾水平右对齐“Shipping List is Finalized Everyday at 5pm EST”。

到目前为止，我已经将 label 标签和两个 input 标签对齐到我想要的位置，但是 span 标签没有对齐完全在右侧。我正在使用引导程序 4.1.1。

这是我的代码：

.main {
  margin: 15px 0;
}

.btn-appear {
  color: #000000;
  background-color: #e6e6e6;
  border: 3px solid #b3b3b3;
}

.btn-appear:focus {
  box-shadow: 0 0 0 .1em rgba(186, 208, 226, .5);
}

.btn-appear:active {
  color: #ffffff;
  background-color: #4d4d4d;
  border-color: #bad0e2;
}

<div class="row main" style="background-color: #ffffff">
  <div class="col-12">
    <h3>Shipping / Loading List</h3>
    <div class="">
      <p class="float-left">Select Shipping / Loading Date</p>
      <p class="float-right">Shipping List is Finalized Everyday at 5pm EST.</p>
    </div>
    <!-- Form code begins -->

        <form method="post">
          <div class="form-group">
            <!-- Date input -->
            <label class="control-label d-block" for="date">Date:</label>
            <div class="form-inline d-inline-block">
              <input class="form-control" id="date" name="date" size="10" placeholder="MM/DD/YYYY" type="text" />
              <input class="btn btn-appear" name="submit" type="submit" value="Search">

抱歉，我花了这么长时间才回复我的解决方案。我实际上改变了很多。这是我的解决方案：

.main{
  margin: 15px 0;
}

.btn-appear{
  color: #000000;
  background-color: #e6e6e6;
  border: 3px solid #b3b3b3;
}

.btn-appear:focus{
  box-shadow:0 0 0 .1em rgba(186,208,226,.5);
}

.btn-appear:active{
  color:#ffffff;
  background-color: #4d4d4d;
  border-color: #bad0e2;
}
