So, today, 24 July, is the day when the ring comes to Bilbo. How could I know this?
I saw that from calendar of Lord of the Ring. This calendar has been stored inside my Mac. You can also find the calendar here: Macintosh HD ▸ usr ▸ share ▸ calendar. You can use this command line to see the calendar:
cat /usr/share/calendar/calendar.lotr
