The calendar for the year 2007 will be the same for the year 2018.

A year repeats its calendar when:

1. It has the same number of days.

2. The leap year pattern matches (i.e., both are either leap years or non-leap years).

3. January 1st falls on the same day of the week.

Since 2007 was a common year (not a leap year) that started on a Monday, the next time this exact pattern occurs is in 2018.
