The date format is not ISO-compliant. For help
with formatting, see

This error occurs when you provide dates that are not in the
standard ISO-compliant format.
As an example, February 29, 2008, 1:10:30 p.m. in Vancouver
should be expressed as:
2008-02-29T13:10:30-8:00
OR simply:
2008-02-29
The ISO standard is based on Greenwich
Mean Time (GMT). If you're in the Pacific Time Zone, you are 8 hours
off GMT (7 hours off GMT in Daylight Savings). This is indicated by the
"-8:00" in the formula above. If you're in the Eastern Time Zone, you
are 5 hours off GMT (4 hours off GMT in Daylight Savings).
One common reason why this error occurs is:
You entered the date correctly in an Excel-based template and
Excel reformatted your date.
If you are using
Excel to manage your data, you can format your date columns as text to
prevent Excel from automatically reformatting them. To do this:
Go to the Format tool on the shortcut menu and choose
"Cells."
On the Number tab, select "Date."
Choose "Text" to format numbers as
text.
