The year 2019 brings us 5 eclipses which is something people are excited to see. However when an eclipse happens it may or may not be visible in your location. Here's a brief explanation of why:
Eclipses occur for a certain duration of time as the objects involved to make one are also moving in space (via their own respective rotation and revolution). Remember that an eclipse requires an alignment of the light source (Sun) and the object casting a shadow and the object being casted upon (Earth's shadow on the Moon for lunar eclipse, and Moon's shadow on Earth for solar eclipse). So as these objects move they will eventually move out from the configuration needed for an eclipse. So if an eclipse happens while it is away from your side of the globe then you will not see it.
Another thing to note is how big is the shadow being cast. Since the Moon is smaller compared to Earth (and also considering its distance of course) it then casts a small shadow which is not enough to cover all of the Earth's surface (See Moon shadow image by NASA/DSCOVR-Epic Team on the right). This is the reason why a total solar eclipse is only visible over a small region over a short period of time. Now, since the Earth is bigger than the Moon it casts a larger shadow making it visible over larger areas and for longer durations. The duration of a lunar eclipse depends on how close the Moon passes to the center of Earth's shadow.

Update: Jan 7 17:20
I included below two animations of the Dec 26 eclipse from the view of Manila and Balut island. This goes to show that even if you are in the same country the eclipse path differs depending on how far you are from the center of the shadow (shown in red at the diagram above).
Also including an animation for the Lunar Eclipse in July (starting from the penumbral phase down to Moonset). Observers should have a clear view of the horizon to see the most of the eclipse.
