Sunday Sighting Visibility Parameters (May 17)
Calculations provided by the HM Nautical Almanac Office and the New Crescent Society point toward favorable skies for Sunday evening:
| UK Location | Sunset Time (BST) | Moonset Time (BST) | Lag Time & Visibility |
|---|---|---|---|
| London | 20:49 | 22:38 | 1 hr 49 mins (Easily Visible) |
| Birmingham | 21:00 | 22:52 | 1 hr 52 mins (Easily Visible) |
| Manchester | 21:04 | 22:57 | 1 hr 53 mins (Easily Visible) |

Decision Scenarios for Sunday Evening
- Scenario A: Moon Sighted Sunday (Highly Probable)
If the crescent is visually verified on Sunday evening, May 17, Dhul Qa'dah ends at 29 days. 1st Dhul Hijjah will be Monday, May 18, placing Eid al-Adha on Wednesday, May 27. - Scenario B: Complete Visibility Obstruction
In the highly unlikely event that severe conditions prevent any certified visibility across regional tracking systems, the month defaults to a 30-day completion. 1st Dhul Hijjah would be Tuesday, May 19, and Eid al-Adha would fall on Thursday, May 28.
Quick FAQ
Why is a sighting impossible on Saturday, May 16?
The moon's conjunction takes place too late in the evening. At sunset across the UK and the Middle East on Saturday, the moon will either have already set or will remain trapped inside the sun's glare at an altitude of less than 0 degrees, rendering visual or optical detection impossible.
How can I report a confirmed or negative sighting?
UK residents are asked to look at the western horizon immediately after sunset on Sunday. You can log visual confirmations or structural negative reports directly on the official registration portals for ICOUK or coordinate through local validation groups under Wifaqul Ulama.
