World

Web novel 4-8

According to Arisa, 1 year is 10 months, 1 month is 30 days. There is no concept of week, a month is divided by 3 part consisting of upper moon, middle moon and lower moon.

By the way I thought that my clock is off by 4 hours but now I know that one day is 28 hours here. Compared to yearly unit, this world system is shorter for about 4%.

Manga chapter 20.5

1 hour = 70 min

1 day = 28 h

1 month = 30 days

1 year = 10 months = 300 days

around 4% error, in 100 years a 4 years gap opens up.
