ラマダンカレンダー — Tokyo, 日本

The timetable on this page is calculated specifically for Tokyo, 日本 at 35.6895, 139.6917 using the Asia/Tokyo time zone. Sehri is tied to the entry of Fajr and Iftar to sunset/Maghrib; they are not copied from a national timetable.

On the projected first fast, Sehri in Tokyo is 5:09 AM and Iftar is 5:15 PM, giving a calculated fasting window of 12 時間 06 分. By the 30th date in the table, Sehri is 4:38 AM (31 minutes earlier) and Iftar is 5:42 PM (27 minutes later). The fast therefore gets longer by about 58 minutes across the displayed month.

The shortest calculated fast in this table is 12 時間 06 分 on 8 2月 2027; the longest is 13 時間 04 分 on 8 3月 2027. Those figures come from Tokyo’s latitude rather than a country-wide average, which is why another city in 日本 can have a visibly different fasting day.

On Ramadan Day 1, calculated Dhuhr is around 11:58 AM, 2 minutes before 12:00. This clock position reflects Tokyo’s longitude inside the Asia/Tokyo zone; solar events do not necessarily line up with 12:00 on the civil clock.

The Asia/Tokyo offset stays at UTC+9 throughout the displayed Ramadan dates, so there is no daylight-saving clock jump inside this table.

These are the nearest other locations in the site’s 日本 city dataset, measured from the stored coordinates. They are shown because nearby-city differences are a practical way to check whether a timetable has accidentally been copied from another place.

Times use Muslim World League by default. A mosque timetable can differ by several minutes because another Fajr/Isha angle, an Asr convention, rounding or a local safety margin may be used. The calculation method is explained on the Methodology page, and local congregational times should always be checked with your mosque.
