All Travel Tools
โ๏ธ Trip Planning
My Trips
Trips saved in this browser. No account โ not Seyyah.
Travel budget calculator
Add the main trip costs. Totals update in your browser โ nothing is sent to a server.
Trip cost calculator
A fuller cost sheet than the budget calculator โ including shopping, insurance and miscellaneous.
Trip countdown
Set a departure date (and optional time). The timer updates every second in this tab.
Date difference calculator
Enter a start and end date. Months use an average month length of 30.437 days.
๐ Destination Tools
Country travel information
Choose a country from the list. Figures come from a static dataset on this site, not a live government API.
Plug and voltage checker
Compare your home sockets with the destination. Dual-voltage chargers (100โ240 V) usually only need a pin adapter.
Country calling code finder
Search by country name, ISO code, or a number like 44 or +1.
Time zone converter
Pick from and to cities, then a local date/time. Conversion uses your browserโs timezone database.
Travel currency converter
Choose amount, from and to. Live rates are ECB reference mid-points via doviz.dev โ not a bank quote.
๐ฑ eSIM & Mobile Internet
Travel internet
Facts come from Twilightโs country dataset. Product prices are not listed. Link through to calculators and MyEsimGlobal if you need a plan.
How Much Mobile Data Do You Need for Travel?
Move the sliders for the apps you actually use. The result is an estimate in GB, plus a light / medium / heavy band.
eSIM compatibility checker
Pick a brand and a model. We list typical support, then tell you how to confirm on the device โ variants differ by region and carrier.
eSIM vs roaming calculator
Type the roaming total your operator quoted and the eSIM price you were offered. The page only subtracts those numbers.
Travel data usage guide
These are mid-range megabytes per hour of active use. Carriers meter differently; treat them as planning ranges.
eSIM installation guide
Most travel eSIMs are added before you leave, over stable WiโFi. Activation often waits until the phone finds a supported network abroad.
๐ฐ Travel Budget
City daily budget
Figures are stay + food + local transport planning bands for mid-2026. Season and neighbourhood can double them. Not a hotel quote.
Daily travel budget
Pick a style to see a rough daily split for food, stay, local transport and extras. Cities and seasons vary widely.
Group trip expense splitter
Name the people, add amounts they paid, then calculate. Equal split among listed travelers.
Travel tip calculator
Tipping customs differ. This only does the arithmetic โ it does not tell you whether to tip.
Tipping customs
We only list countries we have a cautious note for. We will not invent a required percentage for everywhere.
VAT refund calculator
Enter the purchase amount and VAT rate. Choose whether the amount already includes VAT.
๐ Visa & Travel Documents
Turkish exit fee calculator
Default amount is copied from the GฤฐB May 2026 brochure. Confirm on the Digital Tax Office before you fly. Exemptions exist.
Schengen countries
This is a membership list with a public EU source โ not a visa decision and not a substitute for the 90/180 calculator.
Passport validity checker
Many destinations ask for 3 or 6 months of remaining validity. Enter the period that applies to your trip and interpret the result as a helper only.
Schengen 90/180 calculator
Short-stay visitors are generally limited to 90 days in any 180-day period. Add completed stays, then calculate from โas ofโ today or a future date.
Visa requirement guide
Select nationality and destination to structure your research. We do not return a yes/no visa decision.
๐ Time & Flight
Flight time calculator
Type an IATA code, city or airport name for origin and destination. Duration is a physics-style estimate (cruise speed plus climb/descent), not a booked flight.
Flight countdown
Enter the local departure time as shown on your boarding pass (in this deviceโs timezone unless you convert it first).
Layover calculator
Enter arrival and next departure. If departure is earlier on the clock, we assume the next day.
Airport code finder
Type an IATA code, city or airport name. The list is IATA passenger fields from OurAirports.
Jet lag calculator
Select origin and destination zones plus departure and arrival times. Suggestions are generic and not a treatment plan.
World clock
Add IANA cities, remove any you do not need. The list persists on this device.
๐งณ Packing & Preparation
101 Backpack
Photograph what you pack. Items orbit a quiet sphere โ not a globe.
Packing list generator
Get a starting list for clothes, shoes, toiletries, electronics, documents and extras. Adjust it to your trip.
Travel checklist
Tick items as you pack. The list stays in this browser until you reset it.
Luggage size and weight
Unit conversion is exact. The cabin example is a common European template, not your airlineโs rule. Enter your ticket limits.

FAQ
Is this a booking or visa site?
No. Twilight Travel OS is a set of in-browser calculators. It does not sell tickets or issue visa decisions. English canonical: /travel/. Turkish HTML: /travel/tr/.
Where do exit-fee and Schengen figures come from?
Turkish exit fee follows the GฤฐB 2026 brochure (1,250 TRY). The Schengen list follows the European Commission. Each tool page cites the source.
Do you list live eSIM prices?
No. Product links go to MyEsimGlobal. Twilight does not invent prices.
