There are five date formats that are supported by Mailjet, and your default date property will be displayed in a format based on your country setting (i.e. US will have the default: mm/dd/yyyy).
The five supported date formats:
yyyy/mm/dd hh:nn:ss
Year - Month - Day
Example: “1991/09/26 ” would be equal to “26th of September 1991”.
dd/mm/yyyy hh:nn:ss
Day - Month - Year
Example: “26/09/1991” would be equal to “26th of September 1991”.
mm/dd/yyyy hh:nn:ss
Month - Day - Year
Example: “09/26/1991” would be equal to “26th of September 1991”.
RFC3339
Year-Month-Day time
Example: 2016-10-06T13:39:54Z
Epoch and EpochMS
Seconds
Example: 1475761194000
Please note: The time format (hh:nn:ss) is optional. If a date property is added without time, the default time (00:00:00) will be added to the property.
The supported separators between the year, month and day are:
• Dash “-”
• Dot ”.”
• Forward slash “/”
• The separator for time is the colon “:”
When importing your contacts (via a file or copy/paste), Mailjet will scan the date values using the patterns listed below and choose the closest format from the three supported formats (yyyy/mm/dd, dd/mm/yyyy, mm/dd/yyyy).
Note: Use only one Date format when importing your contacts. If there is more than one Date format is found, an error will occur.
Patterns used to scan the date formats:
• 'yyyy-mm-dd hh:nn:ss'
• 'yyyy-mm-dd hh:nn'
• 'yyyy-mm-dd'
• 'dd-mm-yyyy hh:nn:ss'
• 'dd-mm-yyyy hh:nn'
• 'dd-mm-yyyy'
• 'dd/mm/yyyy hh:nn:ss'
• 'dd/mm/yyyy hh:nn'
• 'dd/mm/yyyy'
• 'dd.mm.yyyy hh:nn:ss'
• 'dd.mm.yyyy hh:nn'
• 'dd.mm.yyyy'
• 'yyyy.dd.mm hh:nn:ss'
• 'yyyy.dd.mm hh:nn'
• 'yyyy.dd.mm'
• 'yyyy.mm.dd hh:nn:ss'
• 'yyyy.mm.dd hh:nn'
• 'yyyy.mm.dd'
• 'yyyy/mm/dd hh:nn:ss'
• 'yyyy/mm/dd hh:nn'
• 'yyyy/mm/dd'
• 'mm/dd/yyyy hh:nn:ss'
• 'mm/dd/yyyy hh:nn'
• 'mm/dd/yyyy'
• 'mm.dd.yyyy hh:nn:ss'
• 'mm.dd.yyyy hh:nn'
• 'mm.dd.yyyy'
• 'mm-dd-yyyy hh:nn:ss'
• 'mm-dd-yyyy hh:nn'
• 'mm-dd-yyyy'
• 'yyyy-mm-ddThh:nn:ss+01:00' (RFC3339)
• Epoch and EpochMS
