With this tool you can calculate after how many days two planets line up again, so that they are standing next to each other when seen from sun. Choose the two planets or enter the cycles to use (confirm with ENTER). The two cycles must be different.
Please note that the results are idealized values: In reality the calculated values may differ a bit.
If you think you have found an interesting day, you can enter that as an absolute verse number in the Versefinder to look up the corresponding Torah verse.
