New cycle of the day in the snowy biome

I had an idea about the weather in Minecraft, specifically a feature about the day and night cycle. This idea I propose may be useful for more people to use the snowy biome. If a player spends one or two days in the snowy biome, then the day and night cycle is lengthened, which benefits the player if they want to either increase the efficiency of their experience farm with the night or take advantage of the day for other activities such as building.
Or it can also be an innate feature of the snowy biome, and not have the need to go all the way to the biome. Thank you for your attention
