Hello @MeganR9766 ,
The following are the accepted formats for Birthdates when importing contacts via file:
MM/DD/YYYY
DD-Month
YYYY-MM-DD
M/D/YYYY
D-Month
YYYY-M-D
YYYY/MM/DD
DD-Month-YY
YYYY/M/D
Some other important notes:
If using Excel to edit and manage the file, the field should be formatted as "Date" or "Custom."
After import, the date in a contact record appears as "Month, Day." We don't store the year.
For more info, please see our article on standard headings and character limits for contact fields, also available via the Help tab in your account.
