Dates and Times Showing Wrong in My App
Dates and times in your app show incorrect values. Events show the wrong day, timestamps are off by several hours, or the same date shows differently in different parts of the app. This is confusing for users and can break time-sensitive features like bookings or deadlines.
Common Causes
- Timezone handling — server stores UTC but the app displays UTC instead of the user's local time
- JavaScript Date parsing inconsistencies across browsers
- Database stores dates as strings instead of proper date types
- Date formatting differs between server and client
- Daylight saving time not accounted for
How to Fix It
- Check if dates are stored as UTC in the database (they should be)
- Make sure the frontend converts UTC dates to the user's local timezone for display
- Use a date library (date-fns, dayjs, luxon) instead of raw JavaScript Date
- Be consistent with date formats throughout the app
- Test with users in different timezones to verify correct display

Hi Im a full stack developer, a vibe coded MVP to Market ready product, I'm here to help
Caio Rodrigues
I'm a full-stack developer focused on building practical and scalable web applications. My main experience is with **React, TypeScript, and modern frontend architectures**, where I prioritize clean code, component reusability, and maintainable project structures.
I have strong experience working with **dynamic forms, state management (Redux / React Hook Form), and complex data-driven interfaces**. I enjoy solving real-world problems by turning ideas into reliable software that companies can actually use in their daily operations.
Beyond coding, I care about **software quality and architecture**, following best practices for componentization, code organization, and performance optimization.
I'm also comfortable working across the stack when needed, integrating APIs, handling business logic, and helping transform prototypes into production-ready systems.
My goal is always to deliver solutions that are **simple, efficient, and genuinely useful for the people using them.**

Sage Fulcher
Hey I'm Sage! Im a Boston area software engineer who grew up in South Florida. Ive worked at a ton of cool places like a telehealth kidney care startup that took part in a billion dollar merger (Cricket health/Interwell health), a boutique design agency where I got to work on a ton of exciting startups including a photography education app, a collegiate Esports league and more (Philosophie), a data analytics as a service startup in Cambridge (MA) as well as at Phillips and MIT Lincoln Lab where I designed and developed novel network security visualizations and analytics. I've been writing code and furiously devoted to using computers to make people’s lives easier for about 17 years. My degree is in making computers make pretty lights and sounds. Outside of work I love hip hop, the Celtics, professional wrestling, magic the gathering, photography, drumming, and guitars (both making and playing them)

I’ve watched the tech landscape evolve over the last decade—from the structured days of Java Server Pages to the current "wild west" of Agentic-driven development. While AI can "vibe" a frontend into existence, I specialize in the architecture that keeps it from collapsing.
My expertise lies in the critical backend infrastructure: the parts that must be fast, secure, and scalable. I thrive on high-pressure environments, such as when I had only three weeks to architect and launch an Ethereum redemption system with minimal prior crypto knowledge, turning it into a major revenue stream.
What I bring to your project:
Forensic Debugging: I don't just "patch" bugs; I use tools like Datadog and Explain Analyzers to map out bottlenecks and resolve root causes—like significantly reducing memory usage by optimizing complex DB joins.
Full-Stack Context: Deep experience in Node.js and React, ensuring backends play perfectly with mobile and web teams.
Sanity in the Age of AI: I bridge the gap between "best practices" and modern speed, ensuring your project isn't just built fast, but built to last.

Get HelpFrequently Asked Questions
Events show one day off for some users. Why?
This is almost always a timezone issue. Dates stored as UTC might display as the previous or next day depending on the user's timezone.
Can a developer fix all the date issues at once?
Yes. A developer can standardize date storage (UTC), add proper timezone conversion for display, and use a consistent date formatting library throughout the app.
