Date fields store a year, month, and day in the Gregorian calendar.
Date format
Because ActivityInfo is used by those coming from a wide range of backgrounds and cultures, often all working together on the same team, we have chosen to use the international standard format for dates everywhere in the application, which is “YYYY-MM-DD”, regardless of the user’s language.
For example, May 31st, 2025 is formatted as “2025-05-31.”
Data entry
Although dates are always formatted in the format YYYY-MM-DD, the data entry interface will attempt to automatically detect a variety of alternate formats, such as “July 15th, 2023” or “15/7/23”.
Desktop data entry
In the desktop interface, the date field includes a drop down calendar that can be used to select a field.
Importing
When importing, we recommend first formatting your data in the unambigous YYYY-MM-DD format.
Limits
Date field values must between 1000-01-01 CE and 9999-12-31 CE.
