How to calculate the time for your first project?

Question

Project management

I plan to make 3 pet projects in 2 months. So far, knowledge is only in python, html, css without additional. libraries.
These are: a store with a database, a blog and import / export of goods, a
telegram bot that collects information from external resources, sorts and gives it to the user, a
parser that collects data from the online store using the scrapy library and saves it.
In addition to this, you need to switch from win10 to ubuntu.

Answer 1

1. Spend a day writing a scope of work for one project.
2. Estimate each project work item in days (in whole working days) as best you can, at least at random, comparing the complexity of the items with each other, but be sure to evaluate.
3. Complete one of the items of the scope of work (in terms of development) and fix how much time it took you to do it.
4. Compare with the planned labor intensity, how many times did you make a mistake?
5. Multiply all the points of the plan by the resulting coefficient.
For professional developers, this coefficient may well be equal to "X" (the developer may not know this, but the project manager knows this very well).
"X" I'll tell you when you write us your result :)
And why go anywhere? Check that all the points of the plan will really give you something.

Answer 2

I think in order to do it all in 2 months, you need to be very productive for all 2 months, devoting 10-12 hours a day.
I recommend finding out what knowledge you need to get for each project and immediately draw up a training plan.

Answer 3

I would like to write to you a lot of useful things, so that reading this you will be filled with hope that you have gained some kind of secret knowledge that will help you do everything quickly and on time, accurately predicting the time.
But there is no such secret knowledge. There are certain ideas and methodologies, but they will not bring any benefit to you now and will only waste your time.
All that will help you now is to take on projects and make them. Take it in turns, do it meaningfully, don't be lazy and don't put it off until the day after tomorrow.
All more or less acceptable estimates will come only with experience in project implementation. When there is already a certain amount of experience behind you, you yourself will have a rough idea of ​​what is done, how and for how much, where there may be plugs, where it is worth investing and which methodologies are better to read additionally.

Answer 4

From Murphy's laws:
Westheimer's rule.
To determine how long a job will take, take
the time you think it will take, multiply by 2, and
change the units to higher units.
So, we set aside two days for a one-hour job.
