HubSpot import error: "Could not parse date"

Your HubSpot import finished, but the errors list says Could not parse date. Here is what HubSpot says it means, a free date checker for your file, and the steps we follow.
What the error means
HubSpot's import troubleshooting article says the file contains a date value that does not match the format you selected during the import. If HubSpot can read the value as a date, it may import it wrong, for example with the day and month swapped. If the swapped day isn't a valid month, HubSpot can't parse it. HubSpot says the affected records were imported, but the date property is empty.

Check your CSV before you re-import
Pick your date column. The checker flags dates that are ambiguous (like 04/05/2026), not real calendar dates, two-digit years, or 5-digit numbers that look like spreadsheet serials. It can convert unambiguous dates to YYYY-MM-DD, which has only one possible reading. Your file stays in your browser; nothing is uploaded.
How we fix it
- Find the date columns that showed up in the HubSpot import errors.
- Run each one through the checker. If your whole file is from one source, pick its day/month order so every value is read the same way.
- Download the converted file, or fix the flagged rows by hand.
- When you re-import, choose the date format in HubSpot's import step that matches the file (YYYY-MM-DD if you used the converter).
- HubSpot's fix: update your import file with the correct value and re-import, or update the property value in the affected records by hand.
