BST to PST Conversion Guide

What is BST to PST Conversion?

BST to PST conversion helps you translate time between British Summer Time and Pacific Standard Time zones. BST is UTC+1 during summer months (March to October) and reverts to GMT (UTC+0) during winter months. PST is UTC-8 during winter months (November to March) and becomes PDT (UTC-7) during summer months. The time difference varies: BST is 9 hours ahead of PST and 8 hours ahead of PDT.

Time Zone Information

British Summer Time (BST): Used in the UK during summer months from the last Sunday in March to the last Sunday in October. UTC+1, switching from GMT (UTC+0) during winter.

Pacific Standard Time (PST): Used on the US West Coast during winter months. UTC-8 from November to March. Switches to PDT (UTC-7) during summer months.

Time Difference: BST is 9 hours ahead of PST (winter) and 8 hours ahead of PDT (summer). This large difference often means same-day scheduling is challenging.

Daylight Saving Time Impact

United Kingdom: Observes BST (UTC+1) from March to October, then GMT (UTC+0) from October to March

Pacific Time Zone: Observes PST (UTC-8) from November to March, then PDT (UTC-7) from March to November

Variable Difference: The time difference changes throughout the year: 9 hours during PST period, 8 hours during PDT period

Conversion Tips & Best Practices

• Both time zones observe daylight saving time, but transition dates may differ slightly

• The 8-9 hour difference allows for reasonable business meeting scheduling

• Late afternoon/early evening BST works well for morning PST/PDT meetings

• UK reverts to GMT (UTC+0) during winter months, not BST

• Pacific Time Zone includes major cities like Los Angeles, San Francisco, and Seattle

• Consider using 24-hour format for clarity when scheduling across these time zones

Choose a date and time in the first column. You’ll see options to enter the time either in BST or PST. Use the dropdown menu to make sure you’re starting from the right timezone.

See It in Action: London to Los Angeles

Answers to What Usually Trips People Up

“Why does the time difference change sometimes?”

Because both the UK and US observe daylight saving time, but they don’t switch on the same weekends. The time difference is either 8 or 9 hours, depending on the date.

“What if I start with Pacific time instead?”

You can! Use the Swap button or change the dropdown to select Pacific time as your starting point. The converter will reverse the math accordingly.

“Do I have to press Convert every time?”

Only if you uncheck the “Auto Convert” box. Otherwise, changes are reflected immediately as you enter them.
