I'm try get the number of days between a date and today but I had the following error "Out of bounds nanosecond timestamp".
new['DME']
0    0021-06-09 00:00:00
1    0021-06-09 00:00:00
2    0021-06-10 00:00:00
3    0021-06-09 00:00:00
4    0021-06-09 00:00:00
5    0021-06-09 00:00:00
today = datetime.datetime.today().strftime ('%Y-%d-%m')
new['Days'] = (pd.to_datetime(today) - pd.to_datetime(new['DME']))
