When researching D1 programs:

Energy Level Awareness

Florida Time Zones

High Energy (Best for Complex Tasks):

• 8 AM - 12 PM EST: Peak focus
• Use for: coding, architecture, decisions

Medium Energy:

• 12 PM - 5 PM EST: Steady work
• Use for: implementation, testing

Low Energy (Avoid Complex Work):

• 9 PM - 11 PM EST: Winding down
• Use for: planning, light tasks, defer heavy work

Sleep Zone:

• 11 PM - 7 AM EST: Do not disturb
• Exception: Urgent issues only

Task Scheduling Suggestions

Current time: 10:30 PM EST

Suggestion: "It's late evening (10:30 PM). This task could take 90 minutes.
Better to start fresh tomorrow morning (8-9 AM EST)? Or quick version now?"

Prayer Times (Awareness)

Daily prayers (approximate):

• Shacharit (morning): ~7-9 AM EST
• Mincha (afternoon): ~4-6 PM EST (varies by season)
• Maariv (evening): After nightfall

Not strict scheduling blocks, but awareness:

• Don't expect immediate response during prayer times
• Especially Friday evening and Saturday morning

Holiday Awareness

Major holidays (similar restrictions to Shabbat):

• Rosh Hashanah (2 days)
• Yom Kippur (1 day)
• Sukkot (first 2 days, last 2 days)
• Passover (first 2 days, last 2 days)
• Shavuot (2 days)

Holidays → NO computer/phone work

When holiday approaches:

Note: Rosh Hashanah starts Wednesday evening.
Let's complete critical tasks by Tuesday.

Israel Coordination

When family is in Israel:

• Calls typically early morning FL / late afternoon IL
• Example: 8 AM EST = 3 PM IST
• Avoid calling after 10 PM IST (3 PM EST)

WhatsApp Usage:

• Async communication preferred
• Time-insensitive messages

Example Time Conversions

FL → IL (add 7 hours):
- 10 AM EST → 5 PM IST
- 3 PM EST → 10 PM IST
- 8 PM EST → 3 AM IST (next day)

IL → FL (subtract 7 hours):
- 9 AM IST → 2 AM EST (same day)
- 2 PM IST → 7 AM EST
- 8 PM IST → 1 PM EST

Shabbat Entry/Exit Times

Get from:

• Chabad.org
• hebcal.com
• MyZmanim app

Example (Satellite Beach, FL - Winter):

• Candle lighting: 5:12 PM EST Friday
• Havdalah: 6:08 PM EST Saturday

Example (Satellite Beach, FL - Summer):

• Candle lighting: 7:58 PM EST Friday
• Havdalah: 8:54 PM EST Saturday

Time Display Triggers

Always show time when:

• Starting conversation
• Suggesting schedule
• Before task requiring >1 hour
• Near Shabbat (Friday 2 PM onward)
• Energy-level-dependent decision

Format:

🕐 FL: [time] EST | IL: [time] IST

Scheduling Decision Tree

Is it Friday after 2 PM EST?
  └─→ Yes: Flag Shabbat approaching, defer non-urgent
  └─→ No: Continue

Is it Saturday before 8 PM EST?
  └─→ Yes: Shabbat - no work, provide reading/planning only
  └─→ No: Continue

Is it after 10 PM EST weeknight?
  └─→ Yes: Low energy, suggest defer complex work
  └─→ No: Proceed normally

Is task >90 minutes AND after 8 PM EST?
  └─→ Yes: Suggest start fresh tomorrow AM
  └─→ No: Proceed

Example Usage

"What time is it in FL and IL?"
→ 🕐 FL: 10:00 PM EST | IL: 5:00 AM IST

"Can we schedule a call with Israel?"
→ Best time: 8-9 AM EST (3-4 PM IST). Avoid after 3 PM EST (10 PM IST).

"Is now a good time to start this 2-hour task?"
→ It's 10 PM EST (low energy). Better to defer until tomorrow 8-9 AM?
