There is a very good Hebrew/Gregorian calendar that you can install on your computer called kaluach. Google them. I really like it. It has an option to minimize to an icon on the taskbar that shows just the day of the Hebrew month. If you select in your city from the city list, it will give you numerous times, including netz, shkiya, sof zman tefilla, etc., and you can pick which shita to follow and it will give you those times. This may not be helpful for Shabbos, but I very much like it for the rest of the week.
Many of the local shuls put out a calendar with times for their area also, like Lilmod said. You can also buy them from a Judaica/book store. Most Jewish newspapers publish candlelighting times in their Friday/weekly editions, but for the end of Shabbos that might be posted there, you have to know which shita they’re using. You might need to do a little math to figure out Rabbeinu Tam if it’s not published there.
