Don't confuse with 一昨昨日 (three days ago) is easily confused with the shorter 一昨日 (two days ago, 'the day before yesterday') because of the overlapping kanji.
一昨昨日 (three days ago) and 昨日 (yesterday, one day ago) both describe recent past days and are sometimes mixed up by learners unfamiliar with the compounding pattern.
