The new spreadsheet can be downloaded from www.horrod.com. The main change is that this version is generic so works for all years. Enter the FY start year (e.g. 2016) and all the dates and titles within the workbook will automatically update. All the 'first Monday' dates of each month will automatically set themselves up too along with the last day of the financial month.
Any problems or questions then please do not hesitate to make contact.
