A month of holidays.
I believe that they are so few. The number may look as if they are sufficient but they are not. I didn't know how they were gone but before I knew it, those thirty days were spent.
My mother who arrived before me, had to leave within another week of staying with us. The leave was granted for two weeks and that was the travel gap to Valtis City.
There are only two journeys to and from the city. Other than these scheduled journeys, more journeys would be added if the need arises but this is not such a time. So she had to leave within a week of my arrival, as the next one would be after another two weeks.
Her leave didn't extend that much.
The work at Valtis City is too important to grant its residents leave for too long. If they were gone for months then their work would be delayed and that can't happen in the military.
