title: Run DAG at specific time each day
body: <p>I've read multiple examples about <code>schedule_interval</code>, <code>start_date</code> and the Airflow docs multiple times aswell, and I still can't wrap my head around:</p>
  <p>How do I get to execute my DAG at a specific time each day? E.g say it's now 9:30 (AM), I deploy my DAG and I want it to get executed at 10:30</p>
  <p>I have tried</p>
  <pre class="lang-py prettyprint-override"><code>
  with DAG(
      &quot;test&quot;,
      default_args=default_args,
      description= &quot;test&quot;,
      schedule_interval = &quot;0 10 * * *&quot;,
      start_date = days_ago(0),
      tags = [&quot;goodie&quot;]) as dag:
  </code></pre>
  <p>but for some reason that wasnt run today. I have tried different <code>start_dates</code> altso <code>start_date = datetime.datetime(2021,6,23)</code> but it does not get executed.</p>
  <p>If I replace <code>days_ago(0)</code> with <code>days_ago(1)</code> it is behind 1 day all the time i.e it does not get run today but did run yesterday</p>
  <p>Isn't there an easy way to say &quot;I deploy my DAG now, and I want to get it executed with this cron-syntax&quot; (which I assume is what most people want) instead of calculating an execution time, based on <code>start_date</code>, <code>schedule_interval</code> and figuring out, how to interpret it?</p>
