Next year you can use the 1996 Nautical Almanac from your book case and correct it with the appendix H quad corrections multiplied by 6 which updates the 1996 to year 2020. You can try it out and confirm using a smart phone app. Lots of choices.I like an app called Nautical Almanac for my Samsung cell phone.
