Some students somehow manage to do their dissertation just in a couple of weeks, while others may work on it over one year. Huge role here plays the area of study and the chosen topic.
Try to find info about how long to write a dissertation other people spent to write their theses on a similar topic. It would be even better if you could find a few of these people and talk to them personally. This way you can ask them what problems they have encountered while completing the thesis, what you need to take into account and ask how long to write dissertation you'll need.
You should correctly calculate how much time you'll need to complete dissertation.
