SAN FRANCISCO (KRON) – New year, new date! 

We’re only two days into 2020, but authorities have already issued a warning on why you shouldn’t be abbreviating the new year. 

The warning: Don’t write the date 1/2/20. 

Instead, write out 2020 in full, so it looks like this: 1/2/2020. 

Authorities said the date is easily changeable and could ultimately be used against you. 

“Example: If you just write 1/1/20, [a scammer] could easily change it to 1/1/2017 (for instance) and now your signature is on an incorrect document,” wrote auditor Dusty Rhodes.
