Frequently asked questions
- What date formats can I type in?
- Most common formats are accepted, including ISO strings, "MM/DD/YYYY", and natural text like "July 5, 2026", since parsing uses the browser's native date parser.

- YYYY (year), MM (month), DD (day), HH (hour), mm (minute) and ss (second), e.g. "YYYY-MM-DD HH:mm:ss".
