Perhaps you find calendars featuring cats, waterfalls or classic works of art an anodyne way to keep track of a passing year. Perhaps you feel the world is a bleak place and your calendar should reflect humanity's capacity for carnage and cruelty. Or perhaps you are looking to stay updated on lucrative global bounty-hunting opportunities.

If any of the above apply, the US National Counterterrorism Centre's calendar may be just what you are looking for to keep organised in 2014.

Helpfully provided in daily planner format since 2003, it features America's most-wanted terrorists along with a helpful toll-free number by which to turn them in. It also documents all attacks that have taken place on each day in history, and warns would-be travellers, analysts, spies or even deskbound Walter Mittys of "dates that terrorists may believe are important if planning attacks to commemorate particular events".

So if you flick to March you are reminded that in historical terms the month begins with the arrest of the alleged 9/11 mastermind Khalid Sheikh Mohammed and ends with a suicide attack on a restaurant in Israel. Only one day in the month, 18 March, is empty of significance.

Key religious and secular dates are also marked, from Eid al-Adha and two dates for Christmas celebrated by different Christian denominations, to Halloween and Saudi Arabia's anniversary of the unification of the kingdom.

Between each week there are features on "all range of issues pertaining to international terrorism: terrorist groups, wanted terrorists and technical pages on various threat-related topics". Mostly these are wanted posters with a US number (1-800-US REWARDS) for phoning in tips potentially worth millions of dollars.

In November there is a summary of the activities of the Pakistani Sunni extremists Lashkar-e-Jhangvi, a recap on terrorism across central Asia and profiles of two men who each have a $5m (£3m) bounty on their head – Doku Umarov, a leader of the Caucasus Emirate group, and Mohamed Makawi Ibrahim Mohamed, a Sudanese citizen who killed two USAid employees in 2008.

The calendar is not exclusively focused on Islamist militants, although they dominate the most-wanted and analysis pages. The diary details decades of bombings and attacks by groups across the political and religious spectrum and around the world, from Colombia and Greece to Sri Lanka and Uganda.

For those who have fully embraced the digital age and left paper planners behind, there is an interactive calendar with a timeline, map and updated profiles, with similar information.
