🔍 Key Concepts

• International Date Line (approximately 180° meridian) and what happens to the date when you cross it going eastward versus westward • Difference between zone time (time zones, ZT) and standard meridians (every 15° of longitude) • How the calendar date changes when crossing from east longitude to west longitude at 0500 ZT on March 17

💭 Think About

• When you cross the 180° meridian going east, do you move the date forward or backward? How many days? • If you are at 0500 on March 17 just before crossing, what happens to the date and time immediately after crossing, assuming the clock stays on the same zone time? • Look at each option: which ones change the date, which change the time, and which change both. Which combination matches what actually happens when crossing the date line eastbound?

✅ Before You Answer

• Be clear whether the International Date Line crossing changes date, time, or both in this type of exam problem • Confirm the rule: eastward across the date line → adjust the date one way; westward → the opposite way. Make sure you recall which is which before choosing • Check that the resulting date/time is only one calendar day different, not more than that, from 0500 March 17
