It seems too early for this, but the 2016 agendas are starting to come out.

No matter how you like to plan, there's something for everyone. If you have a lot of meetings and things to do, I recommend the Day Designer or the Simplified Planner. These both include a schedule to list appointments or meetings, along with checklist of what needs to get done. The Day Designer has a few more spaces for information, such as dollars spent that day and the top three things that need to get done that the Simplified Planner doesn't have. Check out the websites for both and see which may be to your liking; I'd say the DD leans business and the SP leans family activities. 

The Simplified Planner does have a weekly version available, and the Day Designer weekly edition is out in July. 

Don't need quite as much space as the DD or SP and like a touch of color, Kate Spade and Lilly Pulitzer both having something for you. Kate Spade has a cleaner look, mostly just a whimsical cover and a plain interior. They've got four covers and two sizes to choose from. Lilly Pulitzer planners are colorful inside and out, with stickers and new this year, a travel diary. There are three sizes and a million covers. They also released a version that have covered spirals, like the Kate Spade planners.

On a side note, I think this is an off year for both the Kate Spade and Lilly covers. I'm pretty meh on all of them.

Russell + Hazel is a highly customizable weekly planner that's a favorite among my friends in DC ("What happens if you lose your phone!?"). A weekly planner with a daily scheduler, you can add all sorts of things to these chic little binders. You can add an address book section, pockets of all sorts, note paper, etc. 

If you're on a budget, Target carries a great assortment of planners. They carry collaboration with Sugar Paper that's pretty and practical, and the Green Room line is colorful and fun.
