Millions of Scottish voters are flocking to polling centres to declare whether they want their country to remain part of the United Kingdom.
Poll centres opened on September 18 at 7am and will close at 10pm the same day.
The results will start filtering in from as early as 1am. This interactive map shows the estimated declaration times and the estimated electoral population.
The final result is expected to be announced the following morning at 6am.
97% of the Scottish population have registered to vote which is the largest ever electorate in Scotland for an election or referendum.
The high turnout of voters means queues are possible which could delay the result.
It has been said the weather could further delay the result as ballot boxes will be brought to counting centres by land, sea and air.
Recounts will only be allowed at a local level and only on the basis of concerns about process.
The Yes camp is expecting a high percentage of their voters to come from Dundee and Glasgow.
Whereas the No camp believes Edinburgh, Aberdeen and the areas closest to England will show their side the strongest support.
The union between Scotland and England has existed for 307 years but if the result is yes, Scotland will become an independent country on May 5 2016.
