PROBLEM TO BE SOLVED: To allow a user to easily know expected arrival time to a destination. SOLUTION: This navigation system is provided with: an arithmetic processing part 1 calculating the expected arrival time to the destination; and a display 2 displaying the calculated expected arrival time. The arithmetic processing part 1 is provided with a present time detection part detecting a present date and present time. The arithmetic processing part 1 performs steps for: deciding whether the calculated expected arrival time exceeds the date of the present time detected by the present time detectio part or not; calculating an arrival day when deciding the calculated expected arrival time exceeds the date; and displaying the calculated expected arrival day and arrival expected time on a display 2 together.
