Half a year back — six months on, well past the new-job phase.
Type any number to find that date.
Half a year back is when something becomes permanent. The job started 180 days ago is no longer new. The exercise routine isn't a phase. The friendship has tested itself across two seasons. By day 180, you and the situation have either shaped each other or you've drifted apart.
Six months is when the temporary stops being temporary. By day 180, the routines you started have weathered every ordinary disruption — vacations, illness, holidays, weather changes. What survives all of that is no longer experimental. The medical and legal worlds treat 180 days as a meaningful threshold for the same reason. Most chronic-condition follow-ups happen at this interval. Most six-month performance reviews land here. Most 'has this stuck?' questions get answered around now.
Many companies run formal mid-year reviews 180 days into the annual cycle. If you had one 180 days ago, the next one is due.
Six-month check-ins are standard for most chronic conditions, dental cleanings, and post-surgical recovery.
EU visa rules look back 180 days from any entry date. Day 180 back is the start of your rolling window.
US public school semesters are 180 days. The midpoint of a school year falls roughly 180 days back from the year-end.
Six months separated catastrophe from reversal. Pearl Harbor was December 7, 1941. The Battle of Midway, where the US Navy sank four Japanese aircraft carriers and turned the Pacific war, was June 4–7, 1942 — almost exactly 180 days later. Half a year is sometimes the interval where a complete reversal becomes possible.
Here's the corresponding date for each of the days around today:
