将日期道具绑定到多个类

我有一个倒计时组件，并有一个日期道具。我有多个叫做计时器的课程，我有自己的方法，天，等等。你明白了。我所拥有的是ProjectCountdown组件中的静态日期。我希望能够使用多个不同的日期，因此每个项目都有自己的倒计时。

这是代码

ProjectCountdown.vue 

  <template>
    <grid :position="grid">
      <Countdown date="March 20, 2017 12:00"></Countdown>
    </grid>
    </template>

    <script>
    import Grid from './Grid';
    import Vue from 'vue';
    import Countdown from './Countdown';
    export default {
      components: {
        Countdown, Grid
      },
      props: {
        grid: {
          type: String,
        }
      }
    }
    Vue.filter('two_digits', function (value) {
      if (value.toString().length <= 1) {
        return "0" + value.toString()
      }
      return value.toString();
    });
    </script>

Countdown.vue 

    <template>
