The USDA Zone info is a great tool for gardeners to help us estimate your gardening schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Newark you can estimate when it's possible to plant arabis by reviewing the USDA zone info.

Since arabis do well in cold you can plant them much earlier in the year than more sensitive plants.

The last month that you can plant arabis and expect a good harvest is probably September. Any later than that and your arabis may not have a chance to really do well. If you are starting your arabis indoors then you might be able to get away with starting them a couple of weeks earlier.
