# Convert timestamp to pandas datetime object
df['timestamp'] = pd.to_datetime(df['timestamp'])

# Sort dataframe by date
df = df.sort_values(by='timestamp', ascending=False)

# Start date
print(df['timestamp'].min())
# End date
print(df['timestamp'].max())
# Date range is just between minimum and maximum
