The dates are displayed in the Grave Search in a Year-Month-Day (YYYY-MM-DD) format. This approximately follows the ISO 8601 standard, which makes the dates easy to sort.
When we have just Year and Month, but no Day, the Day is represented by "00". If we have Year only, the Month and Day are represented by zeroes. Unknown dates are shown as "0000-00-00". The side effect of this standard is that unknown months and days will be sorted before the first day or the month or the first day of the year.
