⚠️ IMPORTANT: USAGE GUIDELINES If you're planning to use this on a server or modpack, please refer to: https://gamedash43.github.io/dash-mcl-licenses/#usage ![Title Text "Date/Time Display"](https://cdn.modrinth.com/data/cached_images/bdd54d24c2e9cb28c3dd70105bb19c2055ee7335.png) This add-on displays in-game time, weather conditions, weekdays, and dates using a day tracker that accurately mirrors real-world dates. ## 💡 Summary - **Real Calculations, Not Just Tracking** Uses actual calendar formulas to compute the current date on the fly, not just by counting days. - **Corruption-Resistant and Lag-Proof** If a lag spike or scoreboard edit happens, the system quietly fixes itself. All numbers come from live math, not stored “tick counters,” so nothing drifts. - **Leap Year & Weekday Accuracy** Gregorian leap-year logic and weekday math are baked in, so February 29th shows up exactly when it should. - **Player-First Displays** Each player gets a private bossbar that morphs by dimension—Overworld date, Nether distance readouts, End Elytra flight-time, and more—so nobody’s UI clashes in multiplayer. - **Instant Toggle + Addon Hooks** Look straight down, sneak, and hold a clock to hide or show the bar in a split-second. Clean namespaced functions make it easy for other datapacks to use toggles or inject their own info. ## 📜 Features - **Real Calendar Replica:** - Tracks days, months, years, leap years, and weekdays exactly like the real world. - April 6 2025 in-game lands on the same weekday as April 6 2025 IRL. - The date is recalculated every tick, so `/time set` or lag can’t throw it off. - **Holiday Accuracy:** - Calculates movable holidays like Easter, Lunar New Year, and Thanksgiving with the same formulas used in astronomy software. - Ready-made hooks let addon packs fire events on any holiday. - **Dimension-Aware Bossbars:** - **Overworld:** standard date + weather summary. - **Nether:** current coordinates and distance from entrance portal. - **End:** live Elytra flight-time estimate until next repair (Unbreaking factored in). - Every bar is per-player, so what you see never collides with what your friends see. - **Clock+Sneak Toggle:** - Sneak while looking straight down with a clock to show/hide your bossbar instantly—no commands needed. - **Live Weather, Biome & Light Checks:** - Shows clear/rain/thunder, biome temperature class. - **Daily Announcements:** - At dawn (and on join) you’ll get a one-liner with the full date, total day count, and any holiday emoji. - **Display Options:** - An optional resource-pack skin hides the bossbar frame for players who prefer a minimalist look. ## ⚙️ Configuration - **For New Worlds:** - Use the config file located in `data/dash.date/function/config.mcfunction` to set your initial dates. Follow the instructions in the file carefully before starting a new world. - **For Existing Worlds:** - Set the dates using the following scoreboard variables (all in the scoreboard `dash.date_arc`): - `%start.year` and `%display.year` for the year. - `%ani.month` and `%display.month` for the month. - `%ani.date` and `%display.date` for the day. - After updating these values, run `/function dash.date:update` to let the system self-correct. - **Note:** Read the instructions in the config file carefully before creating a new world if you plan on modifying it. - **Player Birthday Event:** - Set your birthday for a special event using: - `/scoreboard players set @s dash.date_bd.month [birthday month]` - `/scoreboard players set @s dash.date_bd.date [birthday date]` ## 🌟 Planned Details - This add-on was designed as an extremely accurate calendar system base with no extra items added to the game. - In development is an additional add-on for this pack that will add a placable calender block that displays the current month, date, and upcoming holidays in a vanilla style. - Future plans include events such as Christmas presents, dynamic Easter egg hunts, and other holiday-themed activities within the add-on for this pack. ## ❓ FAQ

Explained in nerd terms.

Using division and modulo operations, the datapack converts game ticks into a 12-hour clock while computing the day-of-year by summing monthly offsets and adjusting for leap years using the standard 4-100-400 rule. Weekdays are determined with a variant of Zeller’s Congruence, and the daycounter algorithm calculates an absolute day value by summing full-year contributions (with leap day adjustments) and the current day-of-year before subtracting a defined start date. In addition, Easter is determined using a classical algorithm that applies modulo and floor division operations to compute the correct month and day, and the lunar new year is approximated by offsetting the year from 1900, taking the remainder modulo 19, and mapping that result to a specific day-of-year.
