How this service works
Returns the weeks of a year in which the clock difference between the US and Europe (or other pairs) is shifted by daylight-saving changes, so foreign market opens move by one hour.
Output
A list of calendar weeks in the specified year during which the daylight-saving time rules for the selected timezone pair (e.g. US-EU) diverge, causing foreign market open times to shift by one hour. Includes week identifiers and the nature of the shift.
Example use cases
Automated trading schedule adjustment
“Can you tell me which weeks in 2026 the US-EU daylight saving gap kicks in, so I know when the Frankfurt open shifts by an hour relative to New York?”
Algorithmic trading calendar planning
“I'm setting up my trading bot for 2027 — which weeks will the London market open at a different US time than normal because of DST mismatches between the US and UK?”
Annual DST impact report for investors
“Give me all the weeks in 2025 where the clock difference between the US and Europe shifts due to daylight saving, using the US-EU pair.”
Technical details
Endpoint
GEThttps://trading-time-api.onrender.com/v1/dst-gap?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to proactively identify in advance which weeks of a year will have a DST-induced one-hour shift between a US and European (or Australian) timezone pair, rather than checking a single specific timestamp. Prefer this over the point-in-time DST gap check when building annual trading calendars, scheduling algorithms, or batch planning tools that need the full list of affected weeks upfront.
Side effects
- Missing required 'year' query parameter returns a validation error
- Invalid or unsupported 'pair' value returns an error (only US-EU, US-UK, US-CH, EU-AU accepted)
- Non-numeric or out-of-range year value may return a 400 error
- Payment not provided or insufficient USDC balance triggers a 402 Payment Required response
- Service may be temporarily unavailable on Render's free tier (cold start latency or downtime)
