A quick guide to Mahadasha and Antardasha durations and how planetary periods

If life sometimes feels smooth for years and then suddenly stressful, confusing, or fast-moving, it’s not random.
In Vedic astrology, this timing is explained through Mahadasha and Antardasha.
Your birth chart shows what can happen in life.
The Dasha system shows when it happens.
It activates planets one by one, instead of everything at once.
Think of it like this:
Mahadasha is a long time period ruled by one planet.
It sets the overall direction of your life for many years.
During a Mahadasha:
If someone is in Moon Mahadasha, life often revolves around:
Mahadasha answers: “What kind of life phase am I in?”

Antardasha is a sub-period within Mahadasha.
It decides how the Mahadasha expresses itself in daily life.
If Mahadasha is the chapter,
Antardasha is the situation inside that chapter.
Moon Mahadasha + Mercury Antardasha
Life direction stays Moon-like, but daily experience becomes Mercury-driven.
Antardasha answers: “What kind of situations am I dealing with right now?”
Many people say: “I entered a new Mahadasha, but nothing happened.”
That’s normal.
Mahadasha sets the background.
Antardasha starts the movement.
Events build gradually, they don’t appear instantly.
People notice the result, not the process.
Mahadasha explains why life feels a certain way.
Antardasha explains what is happening inside it.
Understanding this alone removes a lot of confusion and fear.
When you know:
You stop asking: “Why is this happening to me?”
And start asking: “How should I handle this phase wisely?”
That’s the real purpose of astrology.
