When reading historical books, how do you keep track of timelines?

I've recently become interested in exploring history. However, though I am usually quick to read and process large amounts of information in other genres, I find myself struggling with the dates in history books. For example, here's a excerpt from the book I'm currently reading [1]:

During this period, tsarist policy was contradictory along its Western borders. In Finland, a Parliament was convened in 1863 for the first time in fifty-four years. In 1860, its own currency, the Finnish markka, was introduced, initially tied to the Russion rouble before being tied to the value of silver from 1865, which enabled the Duchy to trade more easily with the West. By 1906, Parliament had passed 400 separate pieces of legislation, and by 1883, Finnish had equal status as a language to Russian.

It takes me surprisingly long to process this; my mind struggles to put together the timeline and most relevant facts. This style is used throughout the whole book and others like it, where multiple dates (and names or facts) are mentioned in a short piece of text, often in seemingly random order. This makes it difficult for me to truly get something out the book -- either I don't remember the information well afterwards or I can't relax while reading because I'm constantly puzzling it together.

For people more familiar with historical works: are there any tricks to this? Does it perhaps get easier in time, when you become more familiar with the genre (similar to keeping track of the characters in fantasy books like Game of Thrones)? Or do some people have a natural affinity for dates, same as others have a mind for numbers or for languages? Looking forward to hearing your opinions and experiences.

Update: This was my first post here, and I’m loving the thoughtful replies. Here’s a summary of the tips so far:

• Combining specific dates into a higher level time periods, e.g. start/middle/late century.
• Using historical dates with a personal meaning as anchors to keep an overview of the time period.
• Paying special attention to the first line of each paragraph, the first section of each chapter, and the first chapter of each book, which should be a summary of the following paragraph, chapter, and book, respectively.
• Writing or drawing your own timeline of events, outside of the book.
• Adding context information to your own timeline, based on understanding why each event occurred in that time and that way.
