See the current BST and EST time difference, check DST changes, and find the best hours to schedule meetings across both time zones.
BST and EST Difference
View the current time difference between BST and EST, including their active UTC offsets. BST is typically UTC+1 and EST is UTC-5, creating a 6-hour gap when both standard definitions apply.
DST Changes and Offsets
Track how daylight saving time affects BST and EST throughout the year with automatic offset updates. Changes are based on the IANA timezone database, including historical and upcoming DST transitions.

How to Find the Time Difference Between BST and EST
Open the BST vs EST page: Go to
https://www.xconvert.com/time-converter/bst-vs-estto load the comparison grid with BST and EST already shown as separate rows. This view is useful when you need to schedule a call between the United Kingdom and the U.S. East Coast, or coordinate support coverage between teams working across Europe and North America.Add comparison cities: Click + Add City and search for cities that matter to your workflow, such as London, New York, Toronto, or Nassau. This helps if you work in finance, media, consulting, or customer support, where teams in BST locations like the United Kingdom often need overlap with EST locations in the United States, Canada, or the Bahamas.
Select a working window on the grid: Click Select to enter selection mode, then drag across the BST row to highlight a time block in purple and compare it instantly against EST. For example, dragging 9:00 BST to 12:00 BST shows 22:00 EST on the previous day to 1:00 EST, which makes it clear that an early BST morning meeting lands late at night or just after midnight in EST.
Export the result for your team: After selecting the range, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This is especially helpful for remote teams, recruiters arranging interviews, or account managers booking client calls, because everyone receives the same meeting window translated into their local calendar context.
BST vs EST Offset Explained
BST means Bangladesh Standard Time and uses UTC+6. EST means Eastern Standard Time and uses UTC-5. The time difference shown here is -11 hours behind, which means EST is 11 hours behind BST, so when it is 12:00 BST, it is 1:00 EST.
This gap creates a large separation between the workday in BST and the workday in EST. The examples on this page show that 9:00 BST = 22:00 EST (previous day), 15:00 BST = 4:00 EST, and 18:00 BST = 7:00 EST, so a normal daytime schedule in BST often falls overnight or very early in the morning in EST. That matters for cross-border operations such as customer support escalations, offshore development coordination, and international vendor calls.
Both abbreviations are standard-time labels, but seasonal naming changes can affect what you see on schedules and calendars. BST is a standard-time abbreviation; its DST counterpart is GMT, while EST is a standard-time abbreviation; its DST counterpart is EDT. If you are booking meetings around seasonal clock changes in the United Kingdom or in EST regions such as the United States and Canada, confirm whether the calendar invite is showing EST or EDT, because the label used in the invite can change even when the meeting series stays on the same local business schedule.
BST is used in Guernsey, Isle of Man, Jersey, and the United Kingdom, while EST is used in Bahamas, Canada, Cayman Islands, Haiti, Jamaica, Mexico, Panama, Turks and Caicos Islands, and the United States. That makes this comparison relevant for legal services, e-commerce, aviation planning, tourism, and multinational operations where a UK-based team may need to coordinate with partners, customers, or offices across the eastern part of North America and the Caribbean.
Frequently Asked Questions
What is the time difference between BST and EST?
BST is 11 hours ahead of EST, expressed here as EST being -11 hours behind BST. In practical terms, when it is 9:00 BST, it is 22:00 EST on the previous day, so even a morning meeting in BST can fall late the night before for someone in EST.
Is BST ahead of EST or behind EST?
BST is ahead of EST by 11 hours. That means the BST workday starts much earlier relative to EST, and many BST daytime hours map to overnight or pre-dawn hours in EST, which is important when planning interviews, customer calls, or handoffs between teams.
Why does 9:00 BST show as 22:00 EST on the previous day?
The offset difference between the two time zones is large enough that early BST hours cross back into the prior calendar date in EST. That is why 9:00 BST = 22:00 EST (previous day), and it is a common source of scheduling mistakes when people focus on the clock time but miss the date shift.
What are some common BST to EST conversion examples?
Several practical examples make the relationship easy to remember: 9:00 BST = 22:00 EST (previous day), 12:00 BST = 1:00 EST, 15:00 BST = 4:00 EST, and 18:00 BST = 7:00 EST. These examples are useful for planning recurring meetings, especially if a UK-based team wants to know whether an afternoon slot is still within early business hours in EST.
Which countries use BST and which countries use EST?
BST is used in Guernsey, Isle of Man, Jersey, and the United Kingdom. EST is used in Bahamas, Canada, Cayman Islands, Haiti, Jamaica, Mexico, Panama, Turks and Caicos Islands, and the United States, so this comparison is relevant for transatlantic business, tourism, shipping coordination, and regional customer support.
Does daylight saving time affect BST and EST?
Yes, seasonal clock naming matters because the standard-time abbreviations are not always the labels you will see year-round on digital calendars. BST has GMT as its DST counterpart, and EST has EDT as its DST counterpart, so if you are scheduling across seasons, make sure the meeting invite reflects the correct abbreviation shown for that date.
What is the best BST time for a call with someone in EST?
Because EST is 11 hours behind BST, early BST business hours are usually too late at night in EST. Using the examples here, 12:00 BST = 1:00 EST and 15:00 BST = 4:00 EST, so BST afternoon slots may be more realistic than BST morning slots if you need at least some overlap with the EST side.
How do I avoid mistakes when scheduling BST and EST meetings?
Use the visual grid to compare both rows on the same date before sending an invite, especially because the date can shift backward for EST. A quick drag selection from a BST slot immediately shows whether the EST result lands on the previous day, overnight, or during business hours, which is much safer than relying on memory for an 11-hour gap.
