Use groupby with count aggregation

booking = df['New_Booking/Issued Date']
df.groupby([booking.dt.year, booking.dt.month]).count()

Output

                                                 New_Booking/Issued Date
New_Booking/Issued Date New_Booking/Issued Date                         
2021                    9                                              2
                        10                                             3
2022                    9                                              2
                        10                                             3

If the column is not in datetime format, use,

df['New_Booking/Issued Date'] = pd.to_datetime(df['New_Booking/Issued Date'], dayfirst=True)
