If you fill out organizer you must also include the organizer_email field.

Use numeric values to describe the date, e.g. "04/25/2021" and not textual, e.g. "April 25th, 2021".

Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed. If, however, the year is given in a two digit format and the separator is a dash (-, the date string is parsed as y-m-d. To avoid potential ambiguity, it's best to use ISO 8601 (YYYY-MM-DD) dates

Date examples:
04/11/2021 03:00 PM or 11-04-2021 15:00 or 2021/04/11 03:00 PM or 2021-04-11 15:00
