How long does a mandala take to make?

I'm curious to know, how long does the intricate process of creating a mandala typically take? Is it a matter of hours, days, or even weeks? And what factors contribute to the varying lengths of time it may require? Does the complexity of the design, the materials used, or the skill level of the artist play a significant role in determining the duration of this artistic endeavor? I'm eager to gain a deeper understanding of the time and effort that goes into crafting these beautiful and meaningful works of art.
