Astronomical observers in Bangladesh have reported that February 18 will offer a roughly 50-minute favorable window for moon sighting after sunset. According to the Bangladesh Weather Observation Team (BWOT), the moon will remain visible in the western sky for about 50 to 51 minutes after sunset, which is considered a suitable period for naked-eye observation. The new moon will form on the night of February 17, but it will not be visible that day due to its young age.

BWOT stated that sunset in Bangladesh on February 18 will occur at approximately 5:58 p.m., and moonset at around 6:49 p.m., giving a 50-minute observation opportunity. By that time, the moon will be about 24 hours old, making visibility more likely if weather conditions are clear. However, visibility will depend on atmospheric clarity, cloud cover, air pollution, and the observer’s location.

The report also noted that some Middle Eastern countries may attempt moon observation using advanced telescopes. If successful, fasting could begin there on February 18; otherwise, it may start on February 19.
