Question
While crossing the IDL, what changes will you make?
✓
Answer
When you cross the 180° meridian, some precautions need to be taken.
There is a difference of 12 hours from 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 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.
