Tools for Adopting a Pet
Countdown to adoption day, food cost maths, vet record management — the practical side of bringing home a new animal.
Adopting a pet comes with more admin than people expect: calculating how long until adoption day, working out the cost-per-day of different food brands, keeping vet records organised, and figuring out whether that 'premium' food is worth the price jump over a mid-tier brand.
These tools handle the numbers. None of your data leaves the browser.
Our pick
For comparing pet food costs, use our Unit Price Calculator.
Paste in the bag size and price to get a cost-per-100g figure — the only fair way to compare a 1.5 kg bag against a 6 kg bag.
Open Unit Price CalculatorTiming and milestones
Countdown to adoption day, calculate the pet's age, schedule vet visits.
- Countdown TimerCount down to any date and time, second by second. Add a label and share the URL — everything lives in the link, no login required.
- Date Difference CalculatorCalculate the number of days between two dates in three modes: total calendar days (with weeks / hours / years-months-days breakdown), working days (weekends excluded, custom holidays optional), or US business days (federal holidays excluded automatically with observed-day shifts).
- Weekday FinderFind the day of the week for any date, past or future. Also shows ISO week number, day of year, quarter, and leap-year status.
Food and cost comparison

- Unit Price CalculatorEnter multiple products with price and quantity — the calculator ranks them by price per unit (per oz, per lb, per kg, per sheet, whatever) and highlights the best deal.
- Percentage CalculatorEvery percentage calculation in one place: X% of Y, X is what % of Y, change from A to B, add/subtract %, add tax. Runs entirely in your browser.
- Discount CalculatorCalculate sale price and savings for any discount percentage. Includes common presets (10%, 20%, 30%, 50%, 75% off).
