摘要
An electronic tide meter which calculates a high tide time and low tide time with accuracy, and a high tide/low tide calculating method are disclosed. A tide level estimating equation is fixed by performing calendar input and selection of a region through an input section and reading tide data of the selected region from a ROM stored with tide data for each region. First tide data is determined with a first time interval from the tide level estimating equation in the CPU, and further second tide data is determined with a second time interval shorter in time interval than the first time interval. Accordingly, from the first tide level data a range is extracted in which the sign in displacement between those of the first tide level data so that tide data at a fine time interval can be determined only for the range. From the tide level data a high tide time and low tide time is calculated with accuracy.
