Top 11 Free Calendar Tools and Apps in 2018

If you’ve seen the movie “27 Dresses,” you remember the scene where Jane realizes she’s lost her planner, or “date book.” As a perpetual bridesmaid, she was constantly attending fittings, showers and ceremonies and had everything meticulously written in this book. Without it, she was panicked, knowing some obligation was likely to slip through the cracks.

One shtick of this movie romance, problematic as it may have been, was Jane’s refusal to join the rest of society by recording her plans digitally. Not to spoil the ending, but she eventually does succumb when her love interest gifts her a Blackberry phone. A little much for an early relationship gift, but you see where we’re going with this: Digital is inevitable.

In a fast-paced society, plans are constantly changing. Meetings are rearranged and parties are rescheduled and gym classes are canceled. As opposed to scratching out or erasing plans in the heavy paper planner that weighs down your purse or briefcase, consider a digital calendar tool. E-calendars provide for simple switches and no scratch-outs, and allow you to share your plans with friends and family.

The following calendar tools are either free or free for a trial and can help your ever-changing agenda stay organized in one place.
