New year’s block is a condition that usually takes place the first couple of weeks into the new year, in which a person keeps writing in the last/previous year in place of the new one.

New year’s block(新年障礙)是在每年剛開始的那幾周會頻繁發生的一種情況：人們在填寫日期的時候，會在本該寫新年份的地方習慣性地寫上剛剛過去那一年的數字。

For example:

This is my third check today I write in the "old" year! I guess I got new year’s block.

這是今天第三張把日期錯寫成去年的支票了!我猜我是患了新年障礙了。
