dayofmonth() function extracts day of a particular month by taking date as input

Syntax:

 dayofmonth(df.colname)

df- dataframe
colname- column name

from pyspark.sql.functions import dayofmonth
from pyspark.sql.functions import to_date

df1 = df_student.withColumn('day_of_month',dayofmonth(df_student.birthday))
df1.show()

In our example “birthday” column is passed to dayofmonth() function, which extracts day of month from date.Get day of month, day of year, day of week from date in pyspark 2
