Solution
- When you cross the 180° meridian, some precautions need to be taken.
- There is a difference of 12 hours from the Prime Meridian if you go from east or west.
- According to the convention, the start (and end) of a date is considered to be at the 180° meridian.
- Accordingly, an adjustment or change in day and time is made. Thus, while travelling from east to west of IDL, a day is added, whereas while travelling from west to east of IDL, the day remains the same.
