The first day’s youngest crescent moon (Hilal) appears from different places on the earth each month, moving from east to west, as well as from south to north. Looking at the predicted crescent visibility maps for a whole year, it can be seen that from the start of 1439 AH (2018) the first day's Hilal appears on the northern hemisphere almost every month. However, prior to 1439 AH, it used to appear approximately 6 months on the southern hemisphere and the other 6 months on the northern hemisphere.
When the moon is in the northern hemisphere, it is possible to sight the Hilal from the UK horizon, if people make an effort to sight it (weather permitting). However, it should be noted that the lunar year has approximately 6 months that are 29-days and 6-months that are 30-days (in different combinations), which means we should not expect to sight the Hilal on every 29th day!
The predicted date in 1439 AH (2017 - 2018) when the moon is expected to be sighted on the UK horizon are given below (which may be 29th or 30th lunar date):
|Observation Dates (for month)||Observation Dates (for month)|
21 Sep (Muharram)

To make a successful sighting of the Hilal (even if cloudy), it is necessary to plan the observation effectively with the following considerations in mind:
- Identify a high location where the western horizon can be easily seen (down to ground/sea level)
- Make a note of the sunset position on a clear day with respect to the landscape a few days earlier
- Use the Internet or Mobile Phone Apps to note the sunset and moonset times for the location
- On the above dates, look for the Hilal close to the sunset position between the above setting times
- Try to use a suitable Mobile Phone App (eg. GPS Compass) to find the direction in cloudy weather
After your observation submit your result on our website (positive or negative), so it can be taken into consideration by the UK Ulama when making a decision for the start of the new month, InshaAllah.
