Chandra Darshan will be observed on the next day of Amavasya (no moon day). On this day devotees worship lord Chandra to seek his blessings. It is believed that seeing the moon on this day is auspicious.
If you're observing fast, you must abstain from having food and water until the first sighting of the moon after sunset.
Cycle Pure wishes you a blessed Chandra Darshan.
