🕚 Cairo to Dublin Time Converter

Dublin is 2 hours behind Cairo for most of the year: when it is 10:00 am in Cairo it is 8:00 am in Dublin. In offset terms Cairo is on UTC+02:00 and Dublin is on UTC+00:00 in January, and UTC+03:00 and UTC+01:00 in July. The converter above works from your browser’s own time zone data, so the figure it shows is the one in force today rather than the one that was in force when this page was written.

The difference is not constant, because both cities observe daylight saving but not on the same dates. In 2026, Cairo changes on 24 April and 30 October and Dublin changes on 29 March and 25 October. That leaves 5 distinct periods in the year, including 2 short ones of a few weeks, and the table below gives the exact dates. It is the short windows that catch people out: a recurring call booked in one city’s clock silently moves in the other’s.

For arranging anything, the number that matters is the overlap. Cairo works 09:00 to 17:00 and Dublin works 09:00 to 17:30, which leaves 11:00 to 17:00 in Cairo — 09:00 to 15:00 in Dublin — as the window when both are open. That is 6 hours of shared working time. The working weeks differ: Cairo works Sunday to Thursday while Dublin works Monday to Friday, which leaves three shared days at each end of the week and two mismatched ones.

Two local details worth knowing. Egypt reinstated daylight saving in 2023 after eight years without it, so older conversion tables for Cairo are wrong for part of the year. Dublin keeps the same clock as London and switches on the same dates, so the two cities are never an hour apart.

The safest way to write a time for these two cities is to give both, as in "10:00 Cairo / 08:00 Dublin", or to give the UTC offset. Abbreviations are the trap: Cairo is on EET for part of the year and EEST for the rest, and the same three letters are reused in other parts of the world for entirely different offsets.

How it works, step by step

1. Enter a time in Cairo using the 24-hour hour box and the minute box — 15:30 is hour 15, minute 30.
2. Your browser reports the UTC offset in force in Cairo and in Dublin for that moment, so a date near a daylight saving transition is handled correctly rather than with a fixed 2 hour rule.
3. The second offset minus the first gives the difference, which is added to the time you entered. A result past midnight is marked as the next or previous day, because that is where most conversion mistakes live.
4. The panel also shows the current time in both cities, the date in Dublin, and whether the two offices are open at the same moment.
