Time to Move

The article announces the relocation of the UK's high-accuracy 60kHz radio signal, essential for radio-controlled clocks and sundial setting, from Rugby to Anthorn, Cumbria, in March 2007. The signal, previously known as The time from Rugby, will subsequently be referred to as The Time from NPL (National Physical Laboratory).

I Hate Drainpipes!

The author expresses his frustration with unsightly drainpipes and other structural elements that frequently disfigure sundials, particularly mass dials. He presents numerous photographic examples from the UK and Europe, illustrating how these obstructions cast shadows or obscure dials, advocating for greater consideration from builders to protect these historical timepieces.

Church Alignment: Towards Patronal Saint Sunrise?

This research article investigates the theory that churches are aligned towards the sunrise on their patronal saint's feast day, based on a comprehensive survey of 1670 churches. The study considers factors like horizon elevation and calendar drift, concluding that the majority of churches consistently align towards true east, rather than their specific saint's day sunrise.

Simple Delineation of Vertical Declining Dials

This article introduces a user-friendly method for delineating vertical declining sundials using bespoke slide rule-like calculators. These tools determine equivalent latitude and longitude, simplifying the process by eliminating complex trigonometry. The article explains how to use these calculators with standard dialling scales to accurately plot hour and sub-style lines.
