Lunar years around 2019
Lengths differ because a leap month is inserted every two or three years. This is what makes the new year date jump rather than drift.
Why 354 days, and not 365
The Chinese calendar counts lunar months of about 29.53 days. Twelve of them come to roughly 354 days, eleven short of a solar year, so a thirteenth month is inserted every two or three years to keep the calendar aligned with the seasons. At 354 days, 2019 was an ordinary year of 12 lunar months.
This is also why the new year date jumps around instead of drifting steadily: it moves back about eleven days each ordinary year, then forward by roughly nineteen when the leap month arrives.
