Travel, Location & Geography Tools
Fifteen travel and location tools: plan a trip budget and packing list, beat jet lag, time flights across zones, count Schengen days, check passport photos, see FX markups, dialling codes, sunrise and moon phases, coordinates, hikes and flight CO2.
About these tools
Travel plans, passport photos and locations are private, so every tool here runs in your browser. Astronomy is calculated from published algorithms, and reference lists - dialling codes, photo specifications, emission factors - ship with the page, dated and sourced, so nothing is fetched while you use them.
Some rules change and differ by country and airline: visa allowances, baggage limits, passport photo specifications. The tools help you check against the rule, but the authority for your trip is the official source named on each page - confirm there before you travel.

All Travel, Location & Geography Tools
- Trip Budget Planner Plan a trip budget by day and category - transport, stays, food, activities - in multiple currencies at rates you enter, split costs between travellers, and track spending against the plan.
- Travel Packing List Builder Generate a packing checklist from trip length, climate, activities, travellers and luggage type, with quantities scaled to the number of nights, laundry options, tick-off mode and print.
- Jet Lag Adjustment Planner Plan how to shift your body clock for a trip: time-zone difference and direction, a day-by-day schedule for sleep, light exposure and light avoidance before and after the flight, based on published guidance.
- Flight Time Calculator Work out flight duration from departure and arrival local times and time zones, or arrival time from duration, across date lines and daylight-saving changes, with great-circle distance between airports.
- Visa Stay Day Calculator Count days of stay in a rolling window - the Schengen 90 days in any 180, or a limit you set - from your entry and exit dates, see days remaining on any date and the latest safe exit.
- Passport Photo Size Checker Check a passport or visa photo against a country's published size, head-height and resolution rules, with a crop guide overlay, background brightness check and a correctly sized print layout.
- Currency Exchange Fee Calculator Reveal the real cost of a currency exchange: compare the rate you were offered with the mid-market rate you enter, add fixed and percentage fees, and see the total cost and effective markup.

- Sunrise and Sunset Calculator Calculate sunrise, sunset, solar noon, day length, golden hour and civil, nautical and astronomical twilight for any coordinates and date, with a month table - computed in your browser.
- Moon Phase Calculator Find the moon phase, illuminated fraction and age for any date and time, the next new and full moons, and a month calendar of phases - calculated from published astronomical formulas.
- Coordinate Format Converter Convert latitude and longitude between decimal degrees, degrees-minutes-seconds, degrees and decimal minutes, UTM and MGRS on WGS 84, one at a time or in bulk from CSV.
- Elevation Gain Calculator Calculate total ascent, descent, highest and lowest points and gradient from a GPX track or elevation list, with a smoothing threshold to remove GPS noise and an elevation profile chart.
- Hiking Time Calculator Estimate hiking time from distance and ascent with Naismith's rule, Tranter's fitness corrections or Tobler's hiking function, with breaks, daylight check and a leg-by-leg plan.
- Flight Carbon Emissions Calculator Estimate a flight's carbon footprint per passenger from great-circle distance or airports, cabin class and trip type, using published government conversion factors with and without the radiative-forcing uplift.
- Baggage Allowance Planner Check bags against the weight and size limits you enter or a dated preset - linear dimensions, per-bag and total weight, cabin versus hold - and plan what to move between bags to stay within limits.
