Live clocks for Karachi and Toronto, the exact difference as it stands today, a converter preset to this pair, and the full 24-hour comparison table — daylight saving handled on both sides.
Converting from Karachi time
The full day in Karachi on today, with the matching time in Toronto:
| Karachi | Toronto |
|---|
Both clocks above are read live from the IANA time-zone database built into your browser — the same rule set your phone uses. “Difference today” is not a fixed fact about this pair of cities: it is computed from the two zones’ offsets right now, which is why it can legitimately read differently if you open this page in a different month.
Toronto is 9 hours behind Karachi for most of the year. For part of the year — when one city has changed its clocks and the other has not — the gap widens to 10 hours.
The 24-hour table walks the whole of today in Karachi, hour by hour, and prints the matching moment in Toronto — including the rows where Toronto is still on yesterday, or already on tomorrow, which are marked +1 day or −1 day. Those edge rows are exactly the ones people get wrong doing the maths in their head.
Convert any moment between 44 world time zones, with offsets and DST handled.

11:00 PM — that is 9:00 AM in Karachi converted on a January day, when Karachi is at UTC+5 and Toronto is at UTC−5. Check it any time with the converter above: the answer is worked out from the two zones’ offsets on the date you pick, so it stays right when the clocks change.
Yes — the difference changes during the year, on the clock-change dates. Toronto is 9 hours behind Karachi for most of the year. For part of the year — when one city has changed its clocks and the other has not — the gap widens to 10 hours.
The two 9-to-5 working days do not overlap at all: 9:00 AM in Karachi is 12:00 AM in Toronto, and 5:00 PM in Karachi is 8:00 AM in Toronto. In practice, calls between Karachi and Toronto mean an early start on one side or a late finish on the other — use the converter above to find the least painful slot on the exact date.
From timestamps and the IANA time-zone database inside your browser — the live rules for each zone, including daylight-saving start and end dates and southern-hemisphere seasons where relevant. Nothing is hard-coded: open this page on a clock-change day and the clocks, the difference and the 24-hour table all follow the new offsets automatically.
Two offsets and one subtraction — the same method the converter at the top of this page runs:
Take 9:00 AM in Karachi, on a January day, when Karachi is at UTC+5 and Toronto is at UTC−5. Adding the pair’s difference for that date gives 11:00 PM in Toronto. The subtlety is that the difference itself is date-dependent for this pair: repeat the same conversion in a month when one city has changed its clocks and the answer can move by an hour. That is why this page never prints a single fixed “the difference is X” without the word today next to it.
