Master 4 temporal types (DATE, TIME, TIMESTAMP, TIMESTAMPTZ)

Extract date parts efficiently (YEAR, MONTH, DAY, HOUR)

Calculate time differences, intervals, and age

Handle timezones correctly (UTC storage → local display)

Format dates for human readability and machine parsing

Avoid 3 critical timezone bugs: DST transitions, timezone-naive timestamps
