title: How to select month in a pandas date column?
body: <p>I don't know how I can use/extract the month in the <code>highpoint_date</code> column. I don't understand how to use datetime to have only this information. How can I do this?</p>
  <p>I just manually made a new column (last line of code) but I think there must be a quicker and easier technique.</p>
  <p>Code:</p>
  <pre><code>import pandas as pd
  expeditions = pd.read_csv(&quot;https://raw.githubusercontent.com/rfordatascience/tidytuesday/master/data/2020/2020-09-22/expeditions.csv&quot;)
  print(expeditions)
  
  expeditions['month_highpoint'] = expeditions['highpoint_date'].str[-5:-3]
  </code></pre>
