Dehradun DM Holiday Radar
Predictive holiday odds tuned on 10-year Doon valley historical precedents & SACHET feeds.
๐จ Live SACHET & IMD District Alert Feed
Real alert bulletins from NDMA's SACHET portal, matched geographically to Dehradun โ the same location-based lookup the official SACHET site itself uses (see the exact radius in the sync note below), not a text search over district names.

Order Notice Cross-Check
A heuristic red-flag scan of a filename/notice โ not an official verification. Always confirm via SACHET, dehradun.nic.in, or your school.
1. Recycled-year check: Flags filenames or text referencing a year other than the current one.
2. Filename wording: Flags words like "fake", "edited", or "copy" in the filename.
3. File type: Flags anything that isn't a PDF/PNG/JPG.
There is no letterhead, digital-signature, or government-registry check โ treat a "no red flags" result as inconclusive, not confirmation.
Dehradun DM Precedent Archive (Verified from News Reports)
11 real school-closure events, each individually verified against a published news source (linked per row). Covers 2018, 2021, and 2024โ2026 โ 2016, 2017, 2019, 2020, 2022 and 2023 are not included because no verifiable report could be found for those years; we're not filling gaps with guesses.

What This App Can and Can't Verify
During active monsoon spells, misleading screenshots with altered dates circulate on WhatsApp groups. Being upfront about the limits of this tool matters more than looking authoritative โ here's exactly what it does.
No Digital-Signature or Cryptographic Check
This app cannot read a PDF's digital signature or certificate. It only scans the filename and any text you paste for obvious red flags (old years, "fake"/"edited" in the name). A "no red flags" result is not proof of authenticity.
No Live Dispatch Number Lookup
There is no crawler checking dispatch numbers (เคชเคคเฅเคฐเคพเคเค) against dehradun.nic.in or any official registry. Always cross-check a dispatch number on the real portal yourself.
Year/Date Mismatch Warning
If a filename or pasted text references a year other than the current one, it's flagged as possibly recycled โ a useful hint, not a guarantee.
Cross-Device Sync Needs a Real Source
The "Confirm Holiday" action requires you to type where you personally verified the closure. The backend stores that source and syncs the confirmed state to your other devices โ it never confirms a closure on its own.
