Zero Shadow Day in Bengaluru: What You Need to Know (24th April 2025)
On 24th April 2025, Bengaluru will have a special event called Zero Shadow Day at 12:17 PM. During this time, poles and people will not cast any shadows. This happens because the sun will be directly overhead. What is Zero Shadow Day? Zero Shadow Day happens when the sun is at its highest point in the sky, called the zenith. When this happens, shadows fall straight down, making them almost invisible. Where and When Does It Happen? Zero Shadow Day happens in places between the Equator and the Tropic of Cancer. In Bengaluru, it happens twice a year – once in late April and again in mid-August. Other Cities with Zero Shadow Days Chennai and Mangaluru also experience Zero Shadow Day, but at different times. As the sun moves north, similar events happen in other places. A Similar Event: The Summer Solstice On 21st June, during the summer solstice, the sun reaches the Tropic of Cancer. This day marks the end of the sun's northward journey, known as Uttarayana, in the Hindu calendar.

BENGALURU: Bengaluru will experience the ' zero shadow ' phenomenon at exactly 12.17pm on April 24, when the sun is directly overhead, according to scientists at the Indian Institute of Astrophysics (IIA). Niruj Mohan Ramanujam, Head of IIA's Science Communication, Public Outreach, and Education (SCOPE) section, explained that during this event, the sun reaches its zenith, causing vertical objects to cast no visible shadows as they fall directly beneath them. All locations in India situated below the Tropic of Cancer—including Bengaluru, Chennai, and Mangaluru—experience Zero Shadow Day , according to Ramanujam.

As a result, shadows fall directly underneath objects and become invisible to the human eye. Zero Shadow Day isn't unique to Bengaluru. It takes place in all cities located between the Equator and the Tropic of Cancer, including places like Chennai and Mangaluru. In Bengaluru, this phenomenon typically occurs twice a year—around April 24–25 and again around August 18, said Dr. Ramanujam.

This also marks the end of Uttarayana, the northward movement of the sun according to the Hindu calendar. Zero Shadow Day happens when the sun is exactly overhead at noon in certain locations. During this brief period, vertical objects like poles or a person standing straight won't cast a visible shadow. It can be observed only in places between the Equator and the Tropic of Cancer and occurs twice a year in each location. It's a simple but stunning demonstration of how the Earth's tilt and orbit affect how we see the sun.
