7d (7 days) is a column label on cryptocurrency price and market-data sites for figures measured over the most recent rolling seven days, usually the percentage price change and the small trend chart printed beside it. The site compares the current price with the price exactly 168 hours earlier, with times kept in UTC. A week smooths out much of the hour-to-hour noise seen in the 1h and 24h columns, so readers use it to see whether a move is part of a short trend or a one-day spike. It still says little about long-term direction, and a single event early in the window can dominate it. Also see 30d (30 Days) and Volatility.
