Jakarta → London time converter
Instantly compare Asia/Jakarta with Europe/London — live clocks, DST notes, and practical scheduling guidance.
Set the origin time
Type a city name, 3-letter code, or IANA zone (e.g., Asia/Jakarta). The tool accepts live time or any custom time you choose.

One origin expands to multiple destinations. London appears with its current offset and alternative formats (12h, 24h, ISO…).
Check DST & labels
View DST notes for Europe/London, helpful time-segment labels (Morning, Work AM, Evening) and quick actions on each card.

Share a link, copy a time, swap origin/destination, or use the Jet Lag Planner to map schedules across travel days.
What this converter helps you do
- Flexible input Enter a city (Jakarta), a short code, or the IANA zone (Asia/Jakarta). The converter recognizes synonyms and common abbreviations.
- Live & custom modes Switch between live clocks (real-time) and custom times for planning meetings, events, or travel itineraries.
- Action buttons per card Each destination card offers Swap, Copy, Jet Lag Planner, and a DST Checker — plus global Undo/Redo/Reset and Share Link controls.
- Time segment labels Automatic segments like Sleep, Morning, Work AM, Lunch, Work PM, and Evening help you pick times that suit both Jakarta and London.
Smart tips for scheduling
Remember DST in London
London switches between GMT and BST. If you schedule recurring calls, prefer an IANA-based rule (Europe/London) so DST shifts are handled automatically.
Best overlap window
For live meetings, late afternoon in Jakarta tends to match London morning — convenient for business calls without late nights.
Travel and jet lag
Jakarta is UTC+7 and London is typically UTC+0 (or +1 during BST). For eastbound travel from London, plan sleep transitions gradually using the Jet Lag Planner.
Historical nugget
Indonesia spans multiple time zones and never uses daylight saving. Britain adopted standard time earlier, and its seasonal clock changes still affect cross-border scheduling.
Frequently asked questions
What is the usual time difference between Jakarta and London?
Jakarta (Asia/Jakarta) is UTC+7. London uses Europe/London which is GMT in winter and BST (UTC+1) in summer — so the offset is typically +7 or +6 hours depending on DST.
Will the converter handle recurring events across DST?
Yes. Use the IANA zone (Europe/London) when creating recurring times so DST transitions are applied automatically by the tool.
Can I enter an IANA code directly?
Absolutely — the tool accepts city names, abbreviations, and full IANA identifiers like Asia/Jakarta and Europe/London.
How accurate are live clocks?
Live mode syncs to a precise time source and displays real-time clocks for each destination; custom times are calculated deterministically from the chosen origin instant.
Does Jakarta observe daylight saving?
No — Indonesia does not use DST. Only the London side observes seasonal changes, so most adjustments come from Europe/London shifts.
Major City to London Routes
How it works (technical)
- Input parsed as city name, abbreviation, or IANA zone (e.g., "Jakarta", "JKT", or "Asia/Jakarta").
- Origin instant converted to UTC internally, then applied to destination IANA zone (Europe/London) to compute local time and offsets.
- DST is evaluated using the destination zone’s rules (Europe/London), so displayed times reflect seasonal changes automatically.
- Multiple output formats (12h, 24h, ISO, custom) and human-friendly segment labels are generated from the same underlying instant.
