Have you ever wondered how to convert days into months? It can be confusing, especially if you’re not familiar with the different calendar systems.

## Background

Before we dive into the answer, let’s take a quick look at the different calendar systems. There are two main types of calendars in use today: the solar calendar and the lunar calendar. The solar calendar is based on the Earth’s rotation around the sun, while the lunar calendar is based on the cycles of the moon. Most countries use the solar calendar, which has 365 days in a year (366 in a leap year). This calendar is divided into 12 months, with each month having either 30 or 31 days (except for February, which has 28 days in a regular year and 29 in a leap year). The lunar calendar, on the other hand, has 354 days in a year and is divided into 12 lunar months. Each lunar month has either 29 or 30 days, depending on the cycle of the moon.
