The revision date of a chart is printed on which area of the chart?

The revision date of a chart is printed in the lower-left corner. This specific location is standardized for navigational charts, allowing mariners to quickly find and verify the publication date. Understanding the placement of critical information like the revision date is essential because it indicates the last time the chart was updated with new data, which can include changes in navigational aids, depth soundings, shoreline modifications, and other relevant information vital to safe navigation. Being aware of this location helps ensure that seafarers are using the most current and accurate charts while navigating.

While other areas on the chart may contain important information such as the chart title or additional legends and notes, the lower-left corner is specifically designated for the revision date, making it an essential reference point for users of navigational charts.
