Those of us who use the Gregorian calendar, mostly celebrate the New Year on 1 January. The Roman and Julian systems were superseded, I suspect, because they couldn’t pin down a simple concept like when to start the year. The latter moved it about between the beginning and end of March, Easter, September and Xmas Day. I don’t know how they worked out when to sow or harvest, never mind when to pay the milk bill. The haphazard Old Style dates were nailed in place in 1752, when the New Style came into force and made Hogmanay more certain.

Many cultures use other reckoning and celebrate New Year differently, so China, India and Latin America for example, will not necessarily be setting off fireworks at the same time. Nevertheless, making a racket and torching the neighbour’s trees will probably feature as part of the merriment.
Wherever you are in the festival, I wish you peace, love and happiness for the fresh start. I hope that 2017 brings you more beautiful blooms and bountiful crops than experienced ever before. If you are nursing a glass of hooch in hand, slangevar, sláinte, salut, cheers.
