Timeline



There is no official timeline of the Assault Lily setting, nor has the exact date ever been stated in most of the continuities, but thanks to a detailed calendar shown in Episode 5 of Assault Lily: Bouquet we've been able to calculate when this specific moment in Bouquet takes place: June 18, 2052.

An explanation of how this date was calculated
 * The date shown is Tuesday, June 18. This combination of weekday and date narrows the possible years down to 2047, 2052, 2058, and various others.
 * 旧5月22日 means "5/22 in the old calendar" (meaning the lunar calendar used in Japan prior to the adoption of the Gregorian calendar.) Like all lunar calendars, this calendar experiences continuous drift compared to the solar calendar. 6/18/2052 corresponds to 5/22 in the old calendar.
 * 6/18/2047 corresponds to 5/25 in the old calendar.
 * 6/18/2058 corresponds to intercalary month 4 /28 in the old calendar.
 * 月齢 means "moon age", i.e. the number of days since the new moon. This also corresponds best to 2052.
 * On 6/18/2047, the moon will be 25.5 days old.
 * On 6/18/2058, it will be 27.7 days old.
