AnnuCal is a time-first year planner that shows your entire year on a single screen.

Instead of scrolling through endless monthly or weekly views, AnnuCal gives you a visual 12-month layout - so phases, overlaps, deadlines, and free space become obvious before your plans get crowded. Unlike a traditional calendar, AnnuCal lets you mark time first, then add the details. Click a day or drag across a whole period directly on the year view, then add a title, color, or calendar. It's a faster, more natural way to plan across months. Three views for how you think about time:

Linear View - your year as a continuous timeline, ideal for long phases and overlapping plans Vertical View - a familiar month-by-month layout that's instantly clear Weekend View - gives weekly rhythm and weekends more natural weight

Share and embed your plans: Share your full year or an individual calendar tab so others stay aligned without changing your plan Embed your entire year directly into other websites, wikis, or team pages

More features: Plan multiple scenarios with separate calendars and tabs Public and school holidays built directly into the year Adaptive or fixed event sizing for a clean, readable overview Fully usable on iPhone and Android in the browser

Designed for individuals, families, teams, and agencies who plan in spreadsheets today and want a clearer, more visual way to structure time.

s3-lambda features and specs

  • Batch processing of S3 objects
    s3-lambda provides a straightforward way to perform batch operations on large numbers of S3 objects, enabling map, filter, and reduce-style processing over entire S3 buckets or prefixes without writing boilerplate code.
  • Familiar functional API
    The library uses a functional programming paradigm with operations like map, filter, and reduce, making it intuitive for JavaScript developers to process S3 objects using patterns they already know.
  • Built-in concurrency control
    s3-lambda handles parallel processing of S3 objects with configurable concurrency, allowing users to control how many operations run simultaneously and avoid overwhelming AWS resources or hitting rate limits.
  • Context-aware operations
    The library provides a context object within each operation that includes useful metadata about the current object being processed, simplifying access to S3 object properties during transformations.
  • Easy integration with Lambda
    Designed to work seamlessly within AWS Lambda functions, making it straightforward to set up event-driven, serverless pipelines for processing large volumes of S3 data without managing infrastructure.

Possible disadvantages of s3-lambda

  • Unmaintained project
    The repository appears to be no longer actively maintained, with limited recent commits and unresolved issues, which raises concerns about long-term reliability, security patches, and compatibility with newer AWS SDK versions.
  • Limited documentation
    The project's documentation is relatively sparse, lacking comprehensive examples, edge case handling guidance, and detailed API references, which can make it challenging for new users to adopt effectively.
  • AWS SDK version dependency
    The library depends on an older version of the AWS SDK for JavaScript, which may conflict with projects using the newer AWS SDK v3 and could miss out on performance improvements and features in updated SDKs.
  • Limited error handling flexibility
    The built-in error handling mechanisms are relatively basic, and handling partial failures or implementing sophisticated retry logic for individual object operations requires additional custom code from the developer.
  • Narrow scope of functionality
    The library is tightly focused on S3 object processing and does not integrate with other AWS services or provide utilities beyond basic map/filter/reduce operations, limiting its usefulness in more complex data pipeline scenarios.

How would you describe the primary audience of your product?

AnnuCal's answer

Visual planners, freelancers, families, and small teams and agencies who juggle many projects, trips, and goals across the year - including people who plan in spreadsheets today and want a clearer, more visual way to structure time.

What's the story behind your product?

AnnuCal's answer

AnnuCal started with a simple idea: What if we could see our whole year at once?

Tired of cluttered monthly views and scattered planning tools, we built AnnuCal to bring clarity back to yearly planning. Created in Germany by a small independent team, AnnuCal was designed to be clean, calm, and privacy-first - a calm, time-first alternative to overloaded calendars

  • Creative professionals managing multiple projects

  • Families and remote teams planning vacations & workflows

What makes your product unique?

AnnuCal's answer

AnnuCal is a time-first year planner, not another calendar. Instead of weekly or monthly views, it shows your entire year on one screen - so you can spot phases, overlaps, and free space at a glance. You mark time first (click or drag across the year), then add the details. Switch between Linear, Vertical, and Weekend views, plan in separate scenarios, and share or embed your full year - with public and school holidays built right in. GDPR-compliant and hosted in Germany.

Why should a person choose your product over its competitors?

AnnuCal's answer

Most calendar tools focus on short-term scheduling - the next meeting, the next day. AnnuCal helps you see the bigger picture and plan time realistically across the whole year. You can share individual calendar tabs or your full year, and even embed the entire year into other websites and team pages. Plus it's GDPR-compliant, ad-free, and hosted in Germany, so your data stays private while your planning stays simple.
